You have a Walmart run scheduled at 6 AM. We're the back office that thinks like you do.
You already know the playbook: buy on clearance, hold or flip, don't fight slow movers, don't let the books rot. The work is the data — the seven retailers, the sealed-vs-used comps, the part-out floor, retirement signals, and your own inventory turn.
We pulled all of that into a workflow that takes minutes instead of hours. The buys with real spreads surface. The pretty discounts that disappear in fees don't. And the back office quietly stays clean while you do the actual work.
A morning, on the platform
Twenty minutes from coffee to buy
The boring research is done. Every retailer is already scanned. Every spread is already priced. You're reading a sorted list and making decisions.
5:47 AM — overnight drops, already ranked
Overnight drops across every retailer worth checking are aggregated and ranked by spread vs. recent eBay sold price — net of fees. You scroll. You highlight three. The other 200 you would've clicked through, you don't need to.
6:02 AM — buy decision in 90 seconds
Click the candidate. The sealed vs. used eBay split. The part-out floor as Plan B. The Amazon demand trend. Inventory at every other retailer. If the math is real, size the order. If it's thin or slowing, pass.
6:14 AM — alerts on the maybes
Sets that are close-but-not-quite go on the watchlist with a target buy price. When Walmart drops or Target clearances trigger, you find out inside the same hour — not three days later.
9:30 AM — the buy lands in inventory
Drop it into a Brickfolio with cost basis, retailer, and date. Your dashboard now shows unit cost vs. live market value across everything you're holding — sorted by unrealized gain, age in inventory, and theme.
Quarterly — your books aren't a panic
Receipts captured all year. Mileage logged automatically. Sales reconciled with marketplace fees backed out. Quarterly tax estimate already calculated. Schedule C export, one click. Your CPA loves you.
The math, in your situations
Five scenarios you'll recognize
The clearance arbitrage you used to miss
A retail set drops at one retailer. Recent sealed comps say there's real margin. After eBay + payment fees and shipping, you net real money per copy. The feed told you the spread was real before you tied up cash. You stop guessing.
The pre-retirement hold
For Star Wars UCS or large modulars, retirement typically yields a serious lift in the year after EOL. Knowing months early lets you scale at retail or near-retail instead of paying secondary-market premium with everyone else.
Plan B when the box won't move
Sometimes the box won't sell, but the parts will. The set page surfaces BrickLink part-out value and ROI so you know — before you buy — whether breaking the box is a viable backup. Useful for older Technic, Creator Expert, and Ideas where rare parts hold the floor.
The buy you talked yourself out of
A great-looking spread evaporates when you check the demand trend. If a set's ranking has been falling for weeks, that "$30 margin" sits on a shelf for six months while listing fees and storage eat it. The data talks you out of bad buys, not just into good ones.
The sealed-vs-used trap
The eBay sold detail splits sealed and used cleanly. A set that looks great on used comps may be priced 25–40% lower sealed — important if you're sourcing retail, because retail-fresh stock only competes with sealed comps. Reading the wrong row is one of the most common reseller mistakes.
Common reseller themes we cover in depth: Star Wars · Modular Buildings · Technic · Architecture · Ideas · Creator Expert · Icons · Harry Potter — and the long tail of Icons, City, Friends, and seasonal lines that quietly print on the right buy.
