If you are looking for a trade value then its usually $.10 for the BTFE & Coke Codes. So you would trade evenly. Many right now are buying the BTFE's in large amounts, but are offering lower than $.10. Stamps is slightlt different.. I usually offer 4 BTFE's per stamp but everyone is different. Find something you are comfortable with and then just stick to it. You will find what works and what doesnt when trying to trade.
