Using A9.com gives you a discount on Amazon
I just noticed today that I am getting a pi/2% discount from my purchases from Amazon because I used a9.com.
Thats a pretty good deal considering I don’t really use A9 that much and was just trying it out. Totally worth setting a cookie or two though. It looks like it can get turned off with lack of use so I might just have to start using it as my default since I am an Amazon-a-holic.
