This has nothing to do with the product itself, everything to do with the cost. Maybe I was just an optimist. The description says four packs when there should be four. It's also a good price, we'd be a good deal in four packs but not three packs. You can get this elsewhere for $7-8 for a full day. You will only receive one package with four pieces in it. I look forward to trying this product if I am not scammed by the seller. I am very upset that I have to pay for the return shipping.
