This deal is mentioned in the '25% Off When You Buy 6 or More Bottles Of Wine at TESCO groceries' thread, but I thought it would make sense to post it separately to make sure people don't miss it.
This deal is for bottles of Hardy's Stamp Cabernet Sauvignon Merlot or Hardy's Stamp Semillon Chardonnay and is on for today and tomorrow only.
The deal is good because you get a double discount, with the 25% off and 2 for £9.00 deals working together:
6 bottles at £6.50 each = £39
- £9.75 (25% off)
- £12.00 (2 for £9.00 discount of £4.00 x 3)
Leaving £17.25 to pay.
This has been confirmed as working in store by nuttybabe and Redfox on MSE.
