Coupon Checker/Database

Hello, My name is Christine. I am a avid couponer, and I am looking to have a personalized app created just for me, and if it takes off also sell. Here is what I am looking for. The name of my app with be Christines List. 1. A app that can scan a coupon bar code and enter in the coupon information into specific fields. You can find an example of this on app Coupons2. See screen shots, 1a. This is a pretty common feature of any coupon bar coding app. 2. I want to then take that coupon and have it search Shoprite online shopping. -go to [login to view URL] - store locator, zip 08540, check off online grocery delivery - Screen shot, shoprite from home 3. When the results come back for the items that match the coupon I would like there to be an option that says add to list, I would like that list to be populated in Google spreadsheet that has the following columns - Item Name, item qty, item price, coupon (auto fills from step 1 information), coupon qty,coupon value (auto fills from step 1 information), total savings, total price, grand total. See screen shot, spreadsheet. This is pretty much stage 1 of what I would like to have done. I have larger ideas of also being able to run this via the web, but do not want to get to ahead of myself since I want to be able to do checking on the fly. I see a coupon in front of me, I scan it, it brings back results of what it can apply to, i see the list and select the item(s) that I want to add to my list. This is more or less right now a personalized coupon database, where all coupons that are entered in manually through the scan. I would like the list of coupons scanned be able to auto check the current prices at the online shopping store each week. Most couponers shop by sales with coupons, well most sales are not advertised, I want to shop by coupons first, and see the cost of the item from there. Please let me know what other questions you have.
