I came by the dollar amounts by looking the titles up on Amazon for the Kindle price if I read a Kindle book and ebook price if it was an epub.
I feel that it is worth the money, but decided that maybe I should be more frugal so I set about trying to find a cheaper card or a card that offers even more titles. I first did a Google search and all of the information in blogs/articles was from the beginning of 2018 or before. I needed updated info. So I began the search by looking up nonresident cards for big cities all around the USA. I discovered that a few libraries will give you one but you must show up to get the card. Not really what I had in mind. A few of them had low fees but the catalog didn't include books I liked to read. I read mostly historical fiction, books on Hollywood stars and Presidents/US history. You may have a completely different taste selection so maybe check out the overdrive for other libraries. The information below was obtained by visiting the library websites.

Illinois nonresident cards are all listed here and range in price. I have not investigated how to obtain the card because the fees were kind of high.
This one doesn't say who can't get a free digital one, but I have a digital-only card at the Campbell County KY. It is a great card and like I said, it is free.
