I agree with "no excuse for not mailing in a padded envelope", especially if the seller charges enough in shipping to cover the cost of a mailer...or some type of padding or protection. Recently, I've received two empty envelopes that clearly showed the outline (in ink) of what once was a chip in the envelope. Both looked like the chip had been ripped from the envelope- by the automatic mail sorter? Both sellers refunded me, but I'd rather have the chips! Yesterday, I received a chip from a fellow member and it was in a regular envelope with no padding...and I paid $2.75 for shipping!! USPS must have a very nice chip collection!!!
