As above in the title popped into morrisons and some big wine offers on. Lots of decent bottles are half price plus the 25% off for 6.
I heard on in-store radio that there is also a voucher in daily mirror for £6 off £60 spend (checked and its valid while end of november)
For example French Connection Cotes Du Roussillon Villages is £10 to £4.99 (which is lovely)
6 bottles would be £22.50
18 bottles with the voucher £61.50, which equates to £3.41 a bottle of quality wine
I couldnt see on the POS when the 25% off finishes
