I was informed that I lost on my bid attempt because my bid was below the seller's minimum, where could I have found out what that minimum was? There was no indication of it on the page where the product was presented

Hello CT,
Thank you for your question about learning where an eBay item's current price is shown. The best way to see this is on the Bid History page for the item, which in this case is the URL below.

We always notify a user if there is an underbid situation, but in this case, as you can see, there wasn't enough time to communicate that you were outbid in time for you to make a change.
Please let us know if we can assist with other questions. We are happy to help.
