I made this to help out a coupon-er I know keep track of her purchases and savings by entering information from receipts. (If you didn’t know, clipping coupons can save you a lot of money, AKA “Oop” – “out of pocket”. Couponers frequently pay a few cents for a load of stuff by buying items when sales coincide with coupons.)
This was also a chance for me to try out wxPython, a pretty slick gui manager. So you could also take a look at this project if you are interested in how to use it to make dialog windows, menus, other simple stuff like that.
