A recent trip to our local ASDA found their bar-coding and till-reading working in their favour.

Expensive convenience packs of washed and bagged salad leaves were marked on the shelf at £1.00, yet the tills were reading the bar-codes as £1.50 and charging customers accordingly.

Fortunately we only bought a few items, so picked up the error. However we doubt that busy shoppers picking up the week’s supply would clock every price on the shelf and check it against the receipt.

Curiously, or perhaps not, we’ve never known these supermarket errors work in the customer’s favour…
