The seller is selling chips, period. Any way found to reduce the necessary evil of shipping expenses should be explored. I have already done the following; I've sent a check to the seller in a USED padded mailer (I use a PO priority label to cover the old addresses and stamp. Of course I cut off the top of the label that says Priority Mail). Inside this used mailer I include my check, a $0.55 stamp and another label to be put over the mailer I just sent him the check in.

Total cost of $1.10 to sent my check and receive the chip.
