Found a great deal on Powerade and a decent deal on Lucozade.
Powerade (all flavours) are buy one get one free. They are 4 packs and cost £2.89. The cheapest deal i've ever seen on these are 2 packs for £4 which was at Somerfield about a month ago (no longer on). So 8 bottles for 36p each is a bargain - even from the cash & carry you wont get them cheaper than 50p each (tried several C&C's...)
Lucozade is 2 x 6-Packs (They had Orange and Original) for £4. So 12 bottles at 33p each.
So if you like Lucozade or Powerade, get down to Morrisons ASAP (my local were running dry).
PS. They have Ben & Jerry's ice cream on special at £1.89 too - be warned, waist expanding!
