We have barcode scanners inside Anaconda, Target, I think Kmart and BigW too. You can check item current price with any today's discounts. Nice.
But no scanners inside Woolworths and Coles. Why is that? Printed shelf labels are often missing, misplaced, confusing or plain wrong. ALDI has no scanners too.
Use case: I see item I want, I cannot find price on the shelf, I go to closest nearby scanner and scanner shows checkout price.
I use the woolies app, can scan from your phone.
