What info does the Nordstrom bar code sticker show from purchase?
If I return a pair of shoes to Nordstrom and they scan the bar code sticker, will the shoe size show up? Or just price? etc?
please include your reference if possible.
thanks

Best answer:

It will know the time/ date you bought the item. The store number and price`paid and whether it was cash or charge.
