Is this blind box trade fair?
Add up what each side is worth, using recent sold prices. If the two sides land within 10% of each other, most collectors would call it fair.
You give $146.00 in value and get $120.00 back.
You'd give about $26.00 more than you get. Ask for a figure or cash to close the gap.
Prices and odds tell different stories
By the odds, a 1 in 72 secret is as rare as about 12 regular figures from a 6-figure series. But the market doesn't price it that way.
On StockX, Have a Seat's secret DuoDuo averages about $146, and a regular figure about $38 to $45. So the price says one secret is worth 3 or 4 regulars, not 12. Trade on prices, and use the rarity number only when no one has sold the figure yet.
Swapping repeats is the cheapest way to finish a set
Every fair swap is a box you don't have to buy, which is $26.99 saved on a Labubu. Trade days are popping up for exactly this, like the Sonny Angel and Smiski meet-ups at Friends NYC in Brooklyn.
The store sums up why they work: "One girlie's duplicate might another's dream pull." Bring your repeats and a list of what you're missing.
Questions collectors ask
Where do I find a fair value?
Look at sold listings, not asking prices, on eBay or StockX. Use the last few sales of the same figure.
Should I add shipping to my side?
Yes, if you're mailing your half. It's money you spend to make the trade, so the calculator adds it to what you give.
