here are not many mom and dad stores out there today. all we find are huge supermarkets stacked up with a lot ofstuff of diferent names and brands of different sizes and prices. it is going to be hard for people who rin the stores to remember all thoe prices, or to note them down on a register andpull them up every time someone wants to buy somethin that has been lying in the ocrner ofthe store for a long time.
well, thankfully we do have computers these days and people now dont even have to take the trouble of punching in the name of the product, they could just use a barcode scanner to feed in the data from the product and that would pull out all details of the product from the database.
