!1 offer hidden. Priced far above the going rate ($56.00–$56.00). That's usually a parked placeholder price from a seller who lists everything that way, or a listing for something else (a variant, a bundle, a plush toy) filed under this item.Show anyway ▾

FAQ
Is it safe to buy with real money?
Mostly yes. Stick to shops with escrow and a real track record and you'll be fine. The offers that go wrong are the ones priced way under market by sellers with no history — we collapse those by default.
Why do prices run $0.50–7.10 per 10K?
7 sellers compete across 4 shops; stock, delivery speed and seller reputation all move the price.
Why are prices per 10K?
Shops sell Boss Key in packs from 60 to 20K. Every listing is converted to a price per 10K so the packs compare. The pack a seller ships is on its row, and the amount table picks the cheapest listing for each pack size.
What's the deal score?
It compares an offer’s price to the market median, then adjusts for seller trust: rating, completed orders, delivery speed and shop protection. Higher is better; the list is sorted by it.
How does delivery work?
The seller hands the item over in-game after checkout. Green dots mean under an hour; amber means the seller quotes longer.
