Schweser Books 2017

Apologies if in wrong place I’m a UK candidate and looking at getting the schweser 2017 level 3 books (have used it solely for other 2 levels with success) The books I have received I appear to be different based on the thinness of pages and some font changes. I was wondering has anyone come across this situation before?

They have pretty good copies of the material here: Click here.

Secondhand materials would be fine (Amazon, Ebay, etc.). They would most likely older versions though. Replica copies are illegal. (Ethics: Knowledge of the Law)

A lot of the stuff on amazon and ebay is counterfeit. The authtnetic Kaplan Schweser material has a silver seal on the back.
