In-store Numbering & coupons

Many stores have weighing machines for meat, produce etc, which print barcode labels.
The label will usually bear price, weight and description of goods in a human readable form and usually barcode 13 bits (a 5 digit product number with 4 digit price, and a country code usually set to "02", and an additional check bit).
