It also benefits the buyer. Your item is worth 20m in the ge but only 15m street price so i will pay 15m cash and 5m junk Isnt it the other way? Like 3a for example, ge the kite is something around ~60m, but street its around ~100m So the seller would put up the kite, 60m, and 40m of random useless junk items The buyer would pay 100m for everything, so the seller gets 100m instead of just the 60 from the ge price of the shield.
