How to make money selling LEGO on eBay comes down to the gap between what you paid and what the exact set sells for after fees and shipping. This week's example is the LEGO Marvel Avengers: Endgame Final Battle (76323), which our members bought on sale at Walmart for about $80. On November 4, 2026, twelve recent sealed, brand-new sales on eBay (October 25 to November 4) ranged from $83 to $109.99, with an average of about $92 and a middle of about $90. After eBay's fees and shipping, that gap is gone. The full set breakdown is in our 76323 price and resale post. This guide uses it to show how to sell things on eBay, LEGO edition. Nothing here is a promise of profit.

Can you make money selling LEGO on eBay?
Yes, but not by buying any new set and relisting it. LEGO sells at a set retail price, and eBay buyers only pay a premium when a set is sold out or retired and people still want it. Right now this one is sold out on lego.com and tagged "Retiring soon," per LEGO's own page, yet eBay prices sit only a little above sale price. That tells you the market already priced the scarcity in. Money in LEGO usually comes from one of three plays:
- Buy on a deep sale well under retail, then sell a sealed set once it is sold out.
- Hold a retiring set for months, since LEGO sets often cost more after they leave the shelves. It ties up cash and is not guaranteed. See how to invest in LEGO sets.
- Use the free-gift and promo angle, covered in our LEGO gift-with-purchase guide.
Step 1: Find the exact sold price
This is where most new sellers go wrong. Asking prices mean nothing, because anyone can list a set for $200.
- Search eBay for the set number ("lego 76323"), not the name.
- Filter to Sold items and condition Brand New.
- Throw out minifigure-only sales, sets with no figures, damaged boxes and multi-set lots. In our check, a copy with no minifigures sold for about $30 and a bundle with another set sold for $124. Neither is the price of one sealed set.
- Look at the last ten or so sales and note the range, not the best one.
- Note where the seller is. Several sales came from Vietnam, Brazil and Australia with import fees due, which is not the US price your buyer pays.
Our own count on November 4, 2026: $83, $85, $86.89, $89.08 (with a seller coupon), $89.99, $90, $90, $95, $95, $95, $100 and $109.99. These are listed prices, and "Best Offer" listings may have closed lower. Early sales in September ran about $65 to $80, so the price has been rising, which is what you hope to see on a retiring set.
Step 2: Do the fee math before you buy
Fees decide everything on a thin margin. We use the formula from our eBay seller fees guide: 13.6% plus $0.40 per order, applied to the sale total. Confirm your own rate in Seller Hub, since it changes by category and seller level.
Assumptions: you paid $80, the buyer gets free shipping, your shipping label and packing cost $10 (our estimate for a mid-size LEGO box, not a quote), and there is no sales tax.
| Sold price | eBay fee | You keep after fee | After $80 buy and $10 shipping |
|---|---|---|---|
| $83 (low) | $11.69 | $71.31 | -$18.69 |
| $92 (recent average) | $12.91 | $79.09 | -$10.91 |
| $110 (high) | $15.36 | $94.64 | +$4.64 |
At these assumptions you would need to sell near $104 just to break even. That is our own arithmetic, not an eBay figure. If you paid $99.99 at retail, it is worse. A set that "sells for more than retail" can still lose money once fees and shipping come out.
Step 3: Decide flip, hold or pass
- Flip it now: no. The numbers above show a loss at the recent average.
- Hold it: this is the play. A sold-out, retiring Marvel set is the pattern our team likes for next holiday season. Holding is a bet, not a sure thing, and your money is stuck until you sell.
- Pass: if you would pay more than about $100 for it.
Step 4: List it so it sells (when you do sell)
- Title: brand, theme, set number, name and condition. For example: "LEGO Marvel Avengers Endgame Final Battle 76323 New Sealed." Buyers search by set number.
- Photos: all sides of the box, showing corners and the seal. Say plainly if there is shelf wear. "Box damage" copies sold lower in our check.
- Item specifics: fill in theme, set number and piece count (621 for this set, per LEGO).
- Price format: fixed price with Best Offer lets you hold your number. Plenty of the sales above closed through offers.
- Shipping: the free-delivery listings are what most buyers compare against, so build the shipping cost into your price.
Step 5: Ship it so it arrives perfect
Sealed LEGO loses value the moment a corner is crushed. Use a box with room for padding, wrap the set, fill the gaps so it can't move, and buy a tracked label. Tracking protects you when a buyer says it never arrived.
What can go wrong
- The price drops when stock returns. Restocks and sales at other stores pull eBay prices down.
- Counterfeits and damage claims. Buyers can open a case if a box is not as described.
- Fees and shipping. The table shows how fast they eat a small gap.
- Time. A hold can last a year or more.
- Taxes. Selling income can be taxable. Ask a tax professional.
Is it worth it?
For this set, not as a quick flip: the average gap is roughly $12 before fees and shipping, and those take more than the gap. It can be worth it as a hold, or on a set you buy well below the sale price. LEGO is a patient category, and the way to learn it is to check sold prices before every purchase. If you haven't opened a seller account, start with how to become an eBay seller, then read how to sell on eBay in 2026 and our LEGO category.
