I joined this about 2 or 3 weeks ago and i’m about 32 points away from getting my first Amazon gift card.
You basically just use their search engine (instead of/before you use google or whatever engine you usually use) and you randomly get reward points for doing so. Once you hit 450 reward points, you get a $5 Amazon gift card.
Amber is already on her 3rd gift card!
Seriously, try it out!
