Do bidders have to enter their payment information every time they make a bid?
Bidder contact and payment information is saved after their first bid is placed. They do not have to enter it each time they place a new bid.
Once a bidder submits a bid on an item in on an auction form, their payment method is saved for future payments on that form. To place a new bid, they can return to the form through the link emailed to them and enter their next bid amount only - no contact information, answers to questions or payment method entry is required.
When a bidder is outbid, they receive an email notifying them that they have been outbid on the item. That email includes a private link to return to the form to place a new bid. This link should not be shared with anyone else.
Every time they visit the auction form from that link, they will land on their personal bidder's view. There, they will see the items they have bid on listed at the top and items they have not bid on yet.
Here is an example:

When they have been outbid, the page will update to show them the new highest bid:

When they place a new bid, they will only have to enter the amount and confirm the bid amount:

They will only be charged if they are the highest bidder on the items they have placed bids on. They will receive emails informing them of whether or not they won the items they bid on.
