I was not saying I want Costco to give me my $20 back. Nor was I saying I would equally exchange my 8GB for a 16GB Touch. I expect Costco to refund me the amount I paid them for the 8GB Touch or I could buy a 16GB Touch from Costco by exchanging the 8GB and paying the price difference.
So I guess I was really asking if Apple will give me my $20 back so I can buy the apps for the new Touch, should they not already come with the ones at Costco. Or will Apple just give me the $20 apps if I buy a newer 16GB version at Costco that doesn't come with them?
