Tesco had packs of 12 x 440ml cans of Magners Irish Cider on a 2 for £15.00 offer. Online, they have now updated the offer to make it 2 for £12.
The original deal worked out at £1.42 per litre / 81p per pint / 63p per can, but now it is £1.14 per pint / 65p per pint.
It should be noted that this offer will only be available in stores that stock these cases, which means it will not show online for everyone. So for example, it is not available online if your delivery store is Exeter Vale, but it is available in store in Honiton
Just to quickly cover a few of the points that always crop up in threads about Magners:
Magners in Ireland is sold under the trade name of Bulmers (totally separate to the Bulmers in the UK). They don't have the right to the name in the UK, so sell it under the name of Magners. (thanks to gratts for this)
Many may consider Magners to be 'an overpriced mass-market fashion drink'. If you feel this way fair enough and you can move on to a deal that interests you.
