To sell a product by auction, it is essential to set it as “Auction” type.
Set the start and end date to let users take part in the auction.
All the bids are listed in the table of the “Bids” tab in the product page.
If you want to encrypt the users’ usernames, disable the “Show full Username in bid tab” entry from the settings dashboard.
When the auction ends, the winner can purchase the product through the “Pay now” button available in the product page.
