I understand that temptation, but know that you might not get any bids when people know that they can buy 8 sheets of these stamps at many stores for the same price you are charging for just 4. If you reduce it, you might have better luck at selling it. People are often willing to pay you for the cost of the stamp, envelope and tracking, but Listia is not intended to be a site where you can make extra money via high shipping cost (in fact, sometimes the moderators will delete auctions if they see sellers trying to do that). Good luck!!
