Just joined today and first post.
My wife spotted this whilst shopping in tesco but the shelves were bare. Checked the website and it's available online for £4.80 for the 8 pack. Not listed in special offers but type in kopparberg in the "I'm looking for" search box and you'll see it.
Usual price is about £1.95 a bottle so even with the £4 delivery it still works out about half price - and much better if you multibuy.
Have ordered 3 lots and hopefully they'll arrive tomorrow - I'll let you know.
