hey peeps asda make barcoding easy!
look at reduced items you can take the barcode sticker off em try it
on another note can the same barcode be re used if its on a sticker
Is this UK Asda? If so be warned its not so simple as each "reduced" label is custom made on the spot for the particular item so it will still show the item/product name when scanned. This is to keep stock inventory correct as it can be.
