Is it okay to do this thing ? (affiliate and adsense)

Hi, I'm running a website and I'm earning money with Google Adsense, and I'd like to add an affiliate links as a store in my website so I can earn more money.

My question is:

Is it okay to use the same description for the product as it is in the original website ? Will I have problems with my Google Adsense considering it as a plagiarism ?!

Note that I'm going to promote books and I need those descriptions.

It is NOT OKAY

Google is very sensitive to information on your website. Specially when you plan to improve your SEO and SEM, you need much more of original content than copies content.

Since Amazon is more popular and ranked higher in SEO, when both your website and Amazon has same content, then your website will be fined or punished for plagiarism and considers Amazon content as original.

If you are looking from legal stand point of view, if the product description was shared by the manufacturer themselves then its purely legal. If the description is of Amazon’s then there might arise a problem take note of your content. They might or might not sue you for copyright infringement laws.
