I actually didn't think my other half got it right until we got to the till with a box of 6 1ltr bottles of Magners and it come up at £12. You do not have to buy 6 as they are being sold in singles for £2each. Amazing. This was in the Basingstoke store, no reason why it would be this store only. Not checked it out online but suggest if you are partial to a magners you get yourself down there first thing before they have all gone.
Just checked online and it is available so you do not even have to go out and take a chance that the shelves are bare. I have also added the link for ease. still in shock as i have never seen this so cheap
