folks on this board could ship so inexpensively (notice I didn't say cheaply) It costs me 10 to 15 cents for a bubble mailer plus $2.07 postage. The chips I have received through purchases have been sent the same way.

Then I received a chip last week in a trade. It was sandwiched between two pieces of cardboard and in a normal sized envelope.
The chip was received in perfect condition. I though the packaging was very clever.

I guess I have been out of it too long. I never thought of using that method to protect a chip.

I thank the trader again, not only for the chip but also for teaching me something.
