@digitoes -
What the barcode will provide is both:
A) Name or product, brand, amount and units
B) A list of prices for that item online and local
With
1) A) I can ask if you want to add a new item and the product, brand, units, etc will
be filled in.
But to select the price you would have to type in the store? Or you could enter
the price yourself?
2) I could provide a list of prices that are online and local, BUT, the list might be
long and might swamp the other prices that you have already entered? Or
3) I could only provide the local prices that are near your GPS location? and
4) Have a switch that allows you to look at online prices?
