I have used Wob several times now. My books have always arrived within a few days, and been in good condition. Wob has become my first choice if I am looking for books, as it is a B-corp and helping to re-use books and cut down on waste, something that I wholeheartedly support. I also recommend it to my friends if they are book-hunting. I haven't tried Ziffit yet, but that also looks great. Keep up the good work!
Thanks for your review :)
