Get My First Book For The Low Price Of $102.50!

This just came across my Google News alerts: my first, self-published book is available on eBay for the low, low price of $102.50, and on Amazon under "New" for up to $142.71.

What. The. Fuck.

Is it because it's out of print, so these booksellers think they can jack up the price? The book is free on Google Books! And having watched old books on Amazon for a while (I collect old art books, among other things), it's interesting that it's not just one seller with an insane price hoping someone misclicks - there's a whole range of prices above cover price, with two in the $100+ range.

Is there some strange aftermarket for that book? Seriously, if you bought my book from eBay or Amazon for anything above cover price, please reach out to me and let me know why!
