Something that has baffled me about these two things. Why do people make steam market listings of items that are in the TF2 Shop when the listing price is higher than the shop price? E.X - Tour of Duty Ticket, market price is 1.33 $, while in the TF2 Shop the price is 1.25 $.

Whether you buy it from the market or shop, you still gotta wait a weak for the temp. untradable tag to disappear...

I have seen people actively buying items from the market when they could buy the same item from the shop for an even smaller price.
