I did try camscanner on a recommendation. Too many ads for my taste. And it was not very clear; very difficult to get a good photo. I tried google drive and it seems to work very easily and well. I might stick with that for a bit unless and until I find something better. Wish google drive worked on a PC with a webcam, though. For some reason they only port their "scan" function to the phones. I can take a photo of the receipt and edit/save it from the laptop, but it's not as simple as using the phone...
