This is so stupid, I sent out 15 sold chips in Bubble Mailers. I have a system, put on return address lable and stamp First Class, on all 15 mailers. Then go to Pay Pal open up payment, write address on mailer, then put in the chip, seal the flap, and put a Scotch tape over the sealed flap. Then go to next sale. Well guess what a buyer sent me an e-mail that he recieved the mailer, but poat office stamped, contents fell out of bubble mailer. Buyer is sending me a photo of mailer, and in second e-mail advised the white tape was still over the glue, and it was never sealed. I've sent out over 4,000 mailers, never had a problem, In my haste I must of not sealed, you would think I would notice when taking to PO? Feel like a fool, told Buyer I have an extra, and will replace with a sealed Bubble mailer. Dumb and Dumber, will never happen again. Ever happen to anyone else?
