Unfortunately no. I've shipped items before for free sometimes even with shipping number that "failed to arrive" even though it was sign for delivery. In other words they cheated me out of the shipping the item and the credits... The way I see it is that if you're willing to pay $5 for shipping then you probably well be honest about receiving a Zippo for shipping + credits involved in the winning of the auction. Considering each credit is worth and half a penny, I think it's one heck of a deal
