In the last 4 weeks I have shopped at Morrisons 3 weekends and each time on a family sized shop I have (or rather the wife has) found errors in the till receipt.
The first week was for £2.70 for cheese, I bought 1 pack and got charged for 2 in different parts of the printout.
Second time was when I bought a pack of 6 tomatoes and my till reciept showed not only the charge for them but also a charge of .79pence for loose tomatoes too which I didnt have.
Lastly today we returned from the same store to find I have been charged for 3 white loaves at .79p each when I only bought 2 loaves. Thats 3 overcharges in the last 4 weekends shopping. The other weekend I shopped elseware.
I did a quick calculation and found that if just this one store overcharged 1000 customers a day by .79p for the year Morrisons would gain over 287 thousand pounds in extra profits, multiply that by the number of stores, lets say there are 300 of them. 86 Million pounds, now thats a nice little earner isnt it!
