So, as I was noodling around with my (now delayed) Goodreads giveaway, I realized that...they sell e-books.
Like, they've been selling e-books for a year now--really explains the problems with Amazon, no?
I Googled it, because I was wondering if this was new. No. It's not. It's been around since before I joined Goodreads. I've been listing and rating the books I read there, and I had no idea they sold anything.
Most of the articles Googled turned up were people saying, "Did you know that Goodreads sells e-books? I had no idea!"
