Made a stop at Carrefour at Porto Cupecoy for a few items today. I could not see what was ringing up but I had a rough idea of what things would cost with the conversion. The cashier was more involved in conversation with the customer behind me and we wanted to get moving so I paid via credit card and we were on our way. Upon getting back, I looked at the receipt and we were charged for 5 items when we only had 4 and 3 of the 4 did not scan properly. Nothing I can do about it now but we paid for an extra item and overpaid for 2 of the 4 we bought and 1 was slightly undercharged. Lesson learned and my fault but we paid about $8 more than the listed prices on the shelf. Next time I will cross check every item and address any discrepancy then.
