The last few weeks, I've really embraced the whole "take a photo of your receipt with your phone and earn cash" apps, particularly ibotta and Snap by Groupon. I just "cashed out" my $10 on ibotta (sent to PayPal) and am working my way toward the $20 cash out minimum for Snap. It does take a little practice snapping photos of your receipts, but you get the hang of it!
If you haven't tried but want to, check them out here:
