It never hurts to make a little on shipping. A lot of people don't realize just how much a 2X2 flip, padded envelope, Printed letter from the seller, tape, address labels and postage cost. Sure some try to take advantage buy charging $5 to ship one chip but I don't think you can do it for much less than $1. And what happens when that one in a hundred get lost in the mail and you have to make good on it?
