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 $5.43–8.10?
10 sellers compete across 2 shops; stock, delivery speed and seller reputation all move the price.
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. The top offer delivers in about 4 minutes. Green dots mean under an hour; amber means the seller quotes longer.
