Which practice test to buy ? or are they the same?

Hello,

I have been looking to by the practice question from Darril Gibson, on his site is $39 SY0-401 Security+ Practice Test Questions | Get Certified Get Ahead

On Amazon is 9.99 - the kindle version.
https://www.amazon.com/CompTIA-Security-Get-Certified-Ahead-ebook/dp/B00Q0HYNAK/ref=tmm_kin_swatch_0?_encoding=UTF8&qid=1496255153&sr=1-2

In terms of the context do you think are the same? Buying one is the same as buying the other one?
Suggestions?

Thank you!
