No matter what you wrap or put the chip in Cardboard, Bubble wrap, Paper, Paper Towel, etc. if you put it in a Regular Envelope,,,,,,,, The Post Office is Gonna Run that sucker through that automatic sorter!!!! I got a package yesterday in a regular envelope and Thank Goodness the member wrapped and taped it in cardboard and it was caught by an "Honest" Postal Worker" or I would have never gotten the chip!! If you want to sell a bunch of chips charge for the shipping. I buy a package of 10 #000 Bubble mailers @ Walmart for $4.44,,,,,, It costs me $.88 cents to mail 1 chip. To me that is worth it to make sure the member gets what he or she paid for or traded for or even if it is a FREEBIE from ME!!!! Call me a fool or whatever,,,,, I appreciate each and everyone of you and I want to make sure I never do anyone wrong in anyway no matter what. Take care & have a great night, Mark
