Here's how I break this down

I only ship with a triple 000 bubble bag, approximate cost 15 cents.
I ship through paypal or ebay and the shipping charge is $1.64.
I place the chip in a small plastic envelope 1 cent..
I wrap it with a quarter panel of flat bubble material 1/4 of a cent.
I wrap that in a folded piece of .923 card board 3 cents.
Since I do not ask and never will for anyone to pay the paypal fees or use gift as a vehicle paypal comes to: 47 cents.
I place a lot of pride in never having to worry about chips arriving in pieces by folks that cut corners when shipping.

When I add all this up it comes to: $2.30 ADD the cost of the chip (1$) and my $6.00 becomes: $2.70 theoretical profit not including tips to valet, cashier cage, gas and wear and tear on the transportation*vbg*

So.........
