Affiliate Marketing Secrets

Hi everyone,
I am building an affiliate website which looks like an e-commerce website. I use amazon, cj and couple of other affiliate programs. The problem is I know google likes unique content, but how do you write a unique product description/review for each product when the brand is same? Maybe has different flavors or colors?
I am not sure if I am allowed to post links here. I would love to get some feedback on my new site.
Thanks!
