Today I was making a purchase on amazon.com and I noticed at the bottom of my purchase a new item that I did not notice before.
I thought that was pretty cool. So, if you make at least one search on A9.com while logged into your amazon.com account you will see an estimated discount applied to your next order (explained). Pretty cool if you ask me.
Oh, yeah, to be nerdy they made the discount π/2% (1.57%).
