Solved: Shopping lists

I wanted a barcode scanner. I don't need one anymore, now that:

• I have a shared google account for everyone in the house
• All of the smartphones and ipads use apps like gtasks to keep in sync
• The smartphone is always available in a pocket and acts as a quick warehouse remote inventory control

While some of the supermarkets are bringing out their own specific apps for shopping lists and prices, using google tasks and similar services for this seems a better fit.

Next on the wanted list:
A google tasks/similar API client that reads all of your tasks, searches google products, and fills in pictures, prices, and other information behind the scenes.
