Folio's selections are extremely curated, so they might not have the specific book you're looking for, but what they do have are all the books that the people around you are reading. The books I ordered were delivered in 3 business days (NYC -> SF) and the shipment included a handwritten note (a touch I always love) and some of the cutest stickers I've seen, the books are stamped Folio on top which are a nice reminder of where I got them. Great alternative to Amazon.
I tried the "Get My Rec!" tool a couple times, but sometimes, I didn't get any results, which was surprising because it's an extremely short survey.
