A program that grants points for using Bing search, which users can redeem for gift cards, sweepstakes entries, or charitable donations.
Excellent questions!
First off, I think downloading the FETCH app and working through that app is the easiest. I found it in the playstore.
At the very least, you will earn 25 points for every scan. I've not had a single scan rejected. The app or should I say through the app, you can see items to purchase that will give you LOTS more points. In my case, things as simple as buying a donut or a 7UP or a Gatorade scores big.
Compared to the Microsoft program, it has much easier to find and earn points.
There is also a FAQ section that I think might answer all your questions.
I hope this helps.
