You must be a registered on Veganbay to bid on items. By bidding, you are stating that you are ready and willing to purchase that item for your bid amount, plus any shipping charges shown in the listing.
If you are outbid, or your bid does not meet the seller's reserve price, you are under no obligation to buy.
In all other cases, you are entering a contract with the SELLER to buy their item, and to deliver payment within the time period specified. If you can't pay, on time, don't bid! Your bids are final and non-retractable unless agreed by SELLER.
