Just seen this online @ Tesco.com and seems like a pretty good deal, similar offers have been running the past few weeks at Tesco. This is a saving of £6, as the original price was £11. This is currently £12 at Asda and a massive £15.49 at Sainsburys, according to mysupermarket.co.uk
Becks Beer 18x275ml bottles for just £5 when you spend £30 or more in a single grocery shop online.
Tennents 18 pack x 440ml cans £5 (from £12) when you spend £30 in-store. Same conditions apply. (This doesn't show up on my online store, so the tennents may be instore only).
* £30 spend does not include the purchase price of the beer. Offer limited to 1 promotional pack per transaction when you spend £30 or more. Subject to availability. Discount deducted at the checkout when you click to buy via this page. You must be 18 years or over to purchase and receive alcohol. Becks 18x275ml £12, 24.2p/100ml. Offer ends 25/8/09.
Also remember "Double Clubcard Points" is on at Tesco too. So your £30 spend will get double points.
