...$14.99 (starting bid) plus $6.25 s&h for a total of $21.24 for the 2 Sands chips. If it's worth $21.24 then bid, if not then pass. If it's worth more then be prepared to bid more.

Would this auction have been more attractive if the starting bid was $21.24 but came with free shipping? ...or if the starting bid was $.01 but shipping was $21.23?

You need to always balance the acquisition price of the item against your out-of-pocket expenses.
