Charge per bid (Penny Bidding)
ℹ️ How it works?
Section titled “ℹ️ How it works?”A Penny product (also known as bidding fee) is a non-refundable product that customers must purchase in order to place bids in a penny auction.
Instead of bidding for free, customers use bidding turns.
Each bid consumes one turn.
Simply put:
- Customers buy Penny products
- Penny products give them a number of bidding turns
- Each bid = 1 turn
- When turns run out, customers must buy more to continue bidding
Why use Penny products?
Section titled “Why use Penny products?”Using Penny products helps you:
- Prevent fake or spam bids
- Ensure bidders are serious and committed
- Earn revenue from:
- bidding fees and
- the final winning bid
In many cases, the total revenue from bidding fees + winning bid can exceed the product’s original price.
