eBay

As a new member of EBay I don't know the rules as yet. I have listed 3 pairs of boots for sale, the bidding has started , does it mean that the bid is for all 3 or just for 1 at a time?

Once the bidding has started can I still sell the product to a customer who wants to pay full price and boy now?

If you bid on a product and there are 3for sale, does it mean that you are bidding for the lot or only one of them.
