Went to Tescos today. Had a walk down the wine aisle just to se if there were any offers. Hardy's stamps of Australia was on offer last week all varieties £3.99 a bottle. I treated myself to a dozen at the time. Anyway they were no longer on offer except for one of the Whites which was still tagged at £3.99. So I popped another half a dozen in the trolley and added a half dozen of an Aussie Shiraz that was also on a reduction. Went to the till and put the wine through as a separate item as we had two £5 off vouchers and so could use one with the wine. The white came through the till at £7.99! So we went to customer services, they checked the shelf price (which should have been removed but was still there) and they had to refund double the difference on the 6 bottles. Thus they refunded me £8 per bottle. So altogther with the refund, the £5 voucher and the 5% discount for buying 6 or more bottles (which was 5% of the full price) we walked out with 12 bottles at an average price of £1.16 a bottle. Result!
