AUCTION
A public sale where items are sold to the highest bidder. Auctions can be conducted live, online, or hybrid (a combination of both).
AUCTION WITH RESERVE
An auction where the seller sets a minimum price that must be met before the item is sold. If bids do not reach this amount, the seller has the right to withdraw the item.

Also known as an absolute auction, this means the item will be sold to the highest bidder, regardless of the price.
