Winning a storage auction unit is the easy part. The real work — and the real skill — is turning those items into cash efficiently. Where you sell matters as much as what you sell. The wrong platform for a given item means either leaving money on the table or spending hours listing something that won't move.
Here's the platform-by-platform breakdown I've refined over dozens of units. Each section covers what sells best there, realistic fee expectations, pricing strategy, and the pitfalls to watch for.
Facebook Marketplace
Best For
Furniture, household items, tools, appliances, sports equipment, and anything large or heavy that's painful to ship. Facebook Marketplace is your primary channel for local sales. If it's bulky and someone would need a truck to pick it up, list it here first.
Fees
No listing fees. No selling fees for local pickup transactions. If you use the shipping option, Facebook takes a percentage, but for storage auction finds you'll almost always be doing local pickup.
Pricing Strategy
Price at 30-40% of retail value for items in good condition. For items with visible wear, drop to 20-30%. The Marketplace audience is deal-hunting — they're not paying near-retail for used goods. Your goal is fast turnover, not maximum per-item revenue.
Mark items as "firm" if you don't want to negotiate, but know that you'll get fewer responses. In my experience, pricing 10% above your actual target and letting people negotiate down works better than pricing firm at your target. People like feeling like they got a deal.
Pitfalls
No-shows are the biggest annoyance. Maybe 20-30% of buyers who say they're coming won't show up. Don't hold items for more than 24 hours unless someone has committed to a specific time. If they go dark, relist immediately. Don't get emotionally invested in any single buyer.
Also: always meet at a public location or at least have someone with you for higher-value transactions. Safety matters more than convenience.
eBay
Best For
Electronics, collectibles, brand-name items, vintage goods, media (games, DVDs, records), and anything with a national or international market. If someone in Kansas would buy this from someone in Florida, it belongs on eBay. eBay's search functionality and buyer base are unmatched for niche and specialty items.
Fees
eBay's fee structure adds up. Final value fees run approximately 13% on most categories (including the payment processing fee). Add shipping costs — which you'll often eat partially or fully to stay competitive — and your actual take-home is roughly 75-80% of the sale price before you factor in packing materials. Know this number before you price.
Pricing Strategy
Always check sold listings (not active listings) to price. What something is listed at doesn't matter — what it actually sold for does. Filter eBay search results by "Sold Items" to see real market value.
For items worth $30+, auction format can sometimes net you more than Buy It Now, especially for collectibles where competitive bidding drives prices up. For commodity items (tools, electronics, household goods), Buy It Now with free shipping tends to sell faster and at more predictable prices.
Pitfalls
Returns. eBay's return policy heavily favors buyers. If someone claims an item is "not as described," you're likely eating the return shipping and the refund. Be absolutely honest in your listings — disclose every flaw, photograph every angle. It's better to undersell in the description and have a happy buyer than to oversell and deal with a return.
Shipping costs will surprise you if you're new to it. Use eBay's shipping calculator and always weigh items before listing. Underestimating shipping on a heavy item can turn a profitable sale into a loss.
Poshmark
Best For
Clothing, shoes, handbags, and accessories — especially brand names. If you find Nike, Lululemon, Coach, North Face, or similar brands in a unit, Poshmark is almost always the best channel. The audience is specifically looking for pre-owned fashion, and they're willing to pay reasonable prices for recognizable brands.
Fees
Poshmark takes a flat $2.95 on sales under $15 and 20% on sales of $15 or more. That 20% is steep compared to other platforms, but the sell-through rate on quality brands is high enough to justify it. You're paying for access to an audience that's actively shopping for exactly what you're selling.
Pricing Strategy
Price at 40-60% of retail for items in good condition. Poshmark buyers expect a discount from retail but they're willing to pay more than Facebook Marketplace buyers because the platform is curated for fashion. Include the brand name, size, condition notes, and measurements in every listing.
Use Poshmark's "Offer to Likers" feature aggressively. When someone likes your item but doesn't buy, send them an offer 10-15% below your listed price. This converts a surprising percentage of window shoppers into buyers.
Pitfalls
Non-brand and fast-fashion items are generally a waste of time on Poshmark. A no-name blouse from Target isn't going to sell for enough to justify the listing effort. Focus on recognizable brands and skip the rest — those items belong in a donation pile or a bulk sale to a local reseller.
Mercari
Best For
A solid all-around platform for items in the $10-$75 range. Mercari works well for home goods, toys, small electronics, books, and mid-range fashion. Think of it as the middle ground between Facebook Marketplace (local, no fees) and eBay (national, higher fees but larger audience). Mercari's shipping is simplified and the buyer base is growing.
Fees
Mercari charges a 10% selling fee plus payment processing. Shipping can be prepaid through Mercari's label system, which makes it easier to calculate your net before listing. Total cost to sell is usually 12-15% of the sale price including processing fees.
Pricing Strategy
Check recently sold items on Mercari for your specific product. Pricing is competitive on this platform — buyers are comparison shopping. Price at or slightly below the average sold price for a quick sale. Mercari rewards active listings and recent posts, so fresh listings get more visibility.
Pitfalls
Mercari's audience is smaller than eBay's. Items that are very niche or very high-value often sell better on eBay where the buyer pool is deeper. Use Mercari for items with broad appeal in the mid-price range and you'll do well.
Craigslist
Best For
Large items, vehicles, heavy tools, and equipment. Craigslist traffic has declined but it's still surprisingly effective for things that are difficult to ship and expensive enough that buyers will drive to pick them up. Riding mowers, workshop equipment, large furniture sets, and anything automotive still perform on Craigslist.
Fees
Free in most categories. Some auto listings now charge a small fee. This is one of Craigslist's remaining advantages — zero selling cost on most items.
Pricing Strategy
Craigslist buyers are bargain hunters. Price slightly higher than Facebook Marketplace since the buyer pool tends to be more serious (less window-shopping, more people with trucks ready to pick up). Include the keyword "firm" or "OBO" (or best offer) depending on whether you're willing to negotiate.
Pitfalls
Scams. Craigslist still has more scam attempts than other platforms. Ignore any buyer who asks you to ship, offers to pay via check or money order, or communicates in a way that feels templated. Cash in person or nothing.
Local Dealers and Shops
Best For
Bulk offloading of specific categories. Antique stores, used furniture shops, used tool stores, record shops, vintage clothing stores, and consignment shops will buy from you directly. They won't pay retail — expect 20-40% of resale value — but they'll take volume and pay immediately.
How to Find Them
Visit local shops and introduce yourself. Tell them you buy storage auctions and you regularly come across items in their category. Ask if they buy from individuals and what their process looks like. Most will. Build relationships with 3-5 dealers across different categories and you'll always have an outlet for items that aren't worth listing individually.
Pricing Strategy
Dealers think in terms of their margin. They need to buy at a price that lets them mark up 100-200% and still sell. If an item retails used for $50, a dealer will pay you $15-$25. That might seem low, but compare it to the hours you'd spend photographing, listing, responding to messages, and meeting a buyer for a $50 sale. Sometimes the dealer price nets you more per hour.
Estate Sale Companies
Best For
When you hit a large unit with diverse, higher-quality contents that would take weeks to sell individually. Some estate sale companies will take consignment lots from storage auction buyers. They handle the pricing, the sale event, and the buyer interactions. You split the proceeds — typically 60-70% to you, 30-40% to the estate sale company.
This only makes sense for units with enough quality and volume to justify the effort from the estate sale company's side. A unit full of generic household goods won't interest them. A unit with vintage furniture, collectibles, artwork, and quality housewares might.
Photography Tips That Actually Matter
Across every platform, photography is the single biggest factor in how fast items sell and how much you get for them. Here's what moves the needle:
- Natural light, always. Take photos outdoors or next to a window. Garage lighting makes everything look worse than it is. This is the single highest-impact change most sellers can make.
- Clean background. A cluttered background makes buyers subconsciously devalue the item. A clean driveway, a white sheet on the ground, or a simple wall works. It takes 30 seconds to set up and it matters.
- Multiple angles. Front, back, close-up of any labels or brand markings, and close-up of any damage. Buyers who can see exactly what they're getting have fewer questions and are more likely to commit.
- Show scale. For items where size isn't obvious from photos, include something for scale — a coin, a hand, a ruler. This reduces returns and reduces the number of messages asking "how big is it?"
- Batch your photos. Set up your photo area, pull out 15-20 items, photograph them all in one session. Context-switching between photographing and listing kills your speed. Batch the photography, then batch the listing.

Matching Items to Platforms — the Quick Reference
When you're sorting a unit, this is the mental framework I use:
- Big and heavy? Facebook Marketplace or Craigslist. Local pickup only.
- Brand-name clothing or accessories? Poshmark first. eBay if Poshmark doesn't move it in two weeks.
- Electronics, collectibles, or niche items? eBay. The national audience is worth the fees.
- Mid-range household items ($10-$75)? Mercari or Facebook Marketplace, depending on whether you want to ship or do local pickup.
- Bulk items in a single category? Call your dealer contact for that category. Instant cash, no listing work.
- High-quality, diverse lot? Consider an estate sale company if the volume justifies it.
- Not worth listing individually and no dealer for it? Donate. Get the tax deduction and free up your space and time for items that actually make money.
The sell side is where most storage auction buyers leave money on the table — not because they can't find buyers, but because they're using the wrong platform for the wrong items or spending too much time on low-value listings. Match the item to the platform, price to move, and don't let inventory sit. Turning cash over quickly is how this business works.
