More sales options

[DarkSheepStudio]

When listing an object for sale, have the option to set the form of sale. Fixed price, auction by bidding, or a combination of both together. Of course, related to this are the options to set the time if only auction is selected so that it doesn't run indefinitely. In the case of a combination of fixed price and auction, the person who buys the item at the fixed price or the highest bidder before the auction ends will get the item. In the case of a fixed price, this is clear for sure. For a better idea, I attach an example below.
