I recently paid $3 S&H on a chip and players card and recieved it promptly... from Hamburg, Germany! As an occasional seller for fun, I don't charge S&H having scored 500 #000 bubble mailers at 1¢ each from a yard sale. I pay postage on my eBay auctions just to move chips across the land.

For the more active sellers who are looking to make a little to pay for their participation in the hobby, it can be a real balancing act but $2.50 is getting a little pushy for a single chip. I also believe that S&H charges should be a required field in the eBay auction template. No entry, no auction!
