I wanted to use a code my friend gave me so I downloaded this app and wanted to check how it worked I snapped a CVS receipt got points, cool. First problem, How do I enter my friends code? I had to look up how to enter a code, should have been there from the start but ok. Second Problem, I can't even find the enter the code button all because I snapped my first receipt! No were on the app it stated what will happen if you snapped your first receipt. Horrible app and stupid rule.
