Have you ever heard of " Swagbucks" "GiftHulk""InstaGC" Tons of others?   They do the same thing through a Browser extension not only do you get a discount you earn 10% in points back that you can redeem for Paypal or gift cards.   Amazon not only allows these programs but endorse them and provide heavy discounted gift cards to the operators do distribute.

They are called " Affiliate Revenue Sharing Programs" and ANYBODY can register and start one.  If the site registered with amazon this way then they are perfectly within their TOS.

Why are you all so determined to do everything you can to prevent success?  Would it bother you that much to be Wrong?
