Kaplan Schweser Notes for Sale

Hi Guys

I am going to be sitting the CFA Level 1 exam in December 2016 and started getting prepped. From what I have read the Kaplan Schweser notes are superior to the official ones provided by the CFA Institute.
I was looking at purchasing the official notes but they are quite pricey for a student. Some guy on eBay is selling the eBooks for £15 and wondering if he is legit. I don’t want to promote his listing, and realise its a long shot but if someone has purchased his notes please let me know the authenticity of his listing.
