Attention Buyer
To ensure that eBay remains a safe marketplace, we limit the amount of items that can be bought or sold by a single account at one time.
You can increase the activity limits on your account by taking the following action:
Verify using a Credit Card
Process is immediate and your card will not be charged.
Note: Some users may need to wait a few minutes for our systems to update before they can bid again. Thank you for your patience.

If I click on "verify using credit card", it asks for my username/password, and after that is entered, it says "unable to process credit card".
Note that it does not ask for any details of my credit card - it just says "unable to process".
So ultimately I am unable to place a bid on the item.
