Fast delivery, especially in comparison to the calculus book I’ve been ordered 9/6/18 and still haven’t received 20 days later when I’m almost quarter done with the semester

Prompt delivery.

Needed for work and appreciate the quick delivery

Prompt delivery

There was a problem with a timely delivery - but I got an apology email and free Amazon Prime delivery to make up for lost time - very much appreciated.

Super fast delivery

It just isn't cost effective as much as I like them.
