How I Turn Retail LEGO Into Resale Profit

Reselling LEGO isn't complicated once you separate two things people confuse: buying and profiting. Buying low is the easy part. Any retiring-soon list will point you at a set on its way out. Profiting is what happens after, and that's where twenty-four years of doing this for a living actually shows up.

My rule: I don't buy a set unless I already know who's going to want it in twelve to eighteen months, and why. Theme-wide retirements (a whole line getting killed, not just one set) tend to hold value best, because the entire shelf disappears at once instead of trickling out. Licensed sets carry the fandom premium longest. Everything else needs a real reason to hold, not just a hope that "it's LEGO, it'll go up."

Where you sell matters as much as what you buy. Amazon FBA and FBM are my biggest channel by far; BrickLink and eBay reach the collectors who pay full secondary-market price on sealed rarities; Facebook Marketplace moves volume fast but at a discount. I've moved over $1M in LEGO inventory across these channels, and the split changes set by set: standard retail sets go through Amazon, sealed UCS pieces go to BrickLink buyers, bulk parts move faster locally.

None of this needs a warehouse or a full-time job. It needs a watchlist, patience past the initial retirement hype, and the discipline to skip sets that don't have a real resale story. That's what the board above tracks — not just what's disappearing, but what's actually worth buying.
