I got the textbook I wanted immediately and saved some money too. No issues so far. (I got it in Feb 2023, reviewing now after checking no issues with credit card). It does help with college and books can be expensive otherwises. Not sure if I can give away but I found a coupon code 'cst10p' (via their twitter) that gives extra discount :)
Tip for consumers: I was able to request them a book which was not originally on their site but they were able to source it for me :)
Simple checkout, got 3 of my ebooks via email immediately. However I mistakenly ordered a different edition and they were kind enough to change it later for me without any extra charges. Saved a lot of money :) :)
Tip for consumers: they also do requests (if you don't find a textbook or testbank on their site, you can request it)
