This was part of our point.

All we wanted was the chip and the seller did nothing to help when it did not show up but throw his hands up and say "not my fault".

And the auction did say:

Buyer to include $2.85 Shipping
Includes Confirmation Signature

Items get lost in the mail, it happens. We have had to replace items before. But we have NEVER just blamed the buyer and said we were not responsible.

And as for listing the EXACT SAME CHIP the day after ebay refunded our money....well that is open to your interpretation, I know what we think happened.
