Sorry if this has already been put up. I did search, but came across nothing. I went to Tesco yesterday and it wasn't advertised, and I went today and it was so I'm assuming it's a new deal that commenced today for this week.
Basically, as the title says, if you spend £30 you can pick up one of the following for an awesome £5. I know they've done it before with just Carlsberg, or just Becks, now you have a choice of 3:
Becks (275ml x 18)
Stella Artois (284ml x 20)
Strongbow (440ml x 15)
I can't find this online on Tesco.com - if someone else does though let me know.
Please note that when you spend £30 you get a £5 'Becks/Stella/Strongbow' voucher for your next purchase, so its not instantly redeemable.
