What trades should I avoid?

Do not trade for anything that cannot be added into the trade offer itself. The most common examples of these scenarios are the following:

• Trading items/gifts for money outside of the Steam Community market. You cannot add Wallet credit, PayPal, gift cards or any form of money into the trade offer.
  
• Trading items/gifts for CD Keys. You cannot add a CD Key into the trade offer. CD Keys that are offered can be for a different game, fake, used or region restricted.
  
• Trading items/gifts for nothing in return in the first trade and expecting to get an item or gift in a later trade. There is no reason to not trade everything in one trade. You may add unlimited items/gifts to a single trade. A common example of this is using a middleman to facilitate a one sided trade.
