That's simply not feasible. The whole reason that the winning price can be so low--often just a fraction of the retail price--is precisely because TCredits are spent on bidding. That's what pays for the products that are auctioned. Without this, this type of auction is not possible. If you are not comfortable with this type of auction, we recommend that you do not participate. Instead, you can use your TCredits on our many other products and available services.
