Very simple application: I want the ability to scan a barcode, and find out if their are coupons for this item, save those coupons, so I can have them scanned when I check out.
For example, if I am at a grocery store, I would like to pick up a box of crackers, scan the barcode, see if their are coupons. If there are save them, so when I can check out I can show the cashier all the coupons.
1) Check into the store I am in using Geo locations
2) scan barcodes of items i plan to purchase
3) do an internet query for coupons for that particular item that will work in that store
4) I can then save the coupons in a folder, so when I am checking out, I can show the cashier all my coupons
