Once upon a time, I had a true-crime review podcast called The Blotter Presents. For various reasons, I no longer do, but I still have a bunch of bee-yoo-tee-full tote bags advertising it.
Yeah yeah, "nobody needs more tote bags" -- but this one is VERY big (18" wide, 13.5" high, 3.5" deep) and has a nice generous handle drop of 11". Speaking of 11, that's how many (mostly hardcover) books I put into it for the picture below -- and there's probably room for at least 3 more!
Sturdily made in the USA, this is a great market or car tote...and if, like me, you rationalize used-book purchases by saying you'll "only" buy what you can fit in your spare bag, well, this tote is a massive loophole. You're welcome!
