Thriftbooks not Amazon. Choose Wisely.…
Service with Thriftbooks has generally been quite good. The books are usually as described concerning condition, and typically ship quickly. I'm not sure when the free book bonus became something you had to use in a certain timeframe, nor what the timeframe might be, but I do know if you're up for a free book you'd best use it before you lose it. It would be nice to have a policy note on that someplace on the site.
