If you receive an invoice and are not done bidding on our auctions, just ignore the invoice, we will send another updated invoice in a few days. For one-time buyers and single purchases we request payment within five days. If you are bidding on multiple auctions please do not go past ten calendar days, it makes the whole billing and shipping process difficult. After ten days non-pays will be reported and the item(s) relisted.
