Just some background info on sales #2 and #3:

In sale #2 both the snack stack and the tank top were valued at QS price (buyout was 35 on the trucker)

Sale #3 was a quicksell as I didn't think I would get more than 10 keys for it and it wasn't worth my time for an extra 2 keys

Even though the low end is based on a quicksell I think this range is still fairly accurate.
