Sam's communicates well. If there is a credit card verification problem, they will E-mail you to resolve the problem. They also notify with a tracking number when they ship. The items arrive gennerally within a week in the midwest. The items have the full Sam's Club Warranty. If you don't like it, or it is defective, they E-mail a return UPS label. I have have never had a problem returning an auction item.
I expect the HID will be on the auction site for a week, or more. The guy who screwed up Dutch auction, I hope was not a CPF member. He was from Racine WI.( a cheese head)
