This happens to me about once a month, and happened again this weekend. On my way home I picked up a 6-pack of beer from the local supermarket. They charge the same for beer from the fridge, as beer (warm) off the shelves, so there is no extra fee for chilled beer.
In the fridge the beer was marked on offer as $5.30 for 2 cans, and 6-packs were marked (no offer-px ticket) as $18.50. So, a 6-pack should be $15.90? I got to the cash-till and the 6-pack was rung up at $18.50. I pointed out the error, the check-out lady went to check the shelves, and the queue behind me begun impatiently sighing.
This happens frequently enough that it now surprises me that the uniform pricing, fridge, px/2, px/6, and ditto on the warm shelves, and then what's programmed in the tills is often not synchronised.
I realise many people wouldn't care about 'a mere $2.60', but I do, it's a basic cock-up and it seems their error always works to their advantage.
Maybe something people might consider if buying products on specials - drinks from fridge vs warm shelves, or confectionery on that specific aisle vs the same products right in front of the tills... It doesn't take a moment to mentally note that 5.3 for 2 * 3 = 15.90, and that's what to expect on the receipt.
--- It goes further, the two customers in front of me had disputes over their receipts and offer-prices too.
- One buying a product she thought was on offer, but it wasn't unless bought together with another product. So that item was taken away, and I don't recall now if she was buying anything else this pm, and if so simply left.
- The second buying 8 of a product, but she wanted to use the '3 for 2' offer or similar, so then the excess 2 units were taken away by the cashier, and had to be refunded off her receipt.
