Seen this in Sainsburys West Belfast today. 6 pack of drinking yoghurts plus 6 free. Priced at £1.89. From what I remember the flavours were strawberry raspberry and vanilla. This offer is also online but I dont know how to add the link properly but if you go on the site and go to groceries- fresh food-drinking yoghurts it should come up.
Also they has 12 packs of Coke, diet coke and coke zero for £2.29 not online so may be store specific as they didnt have the fridge packs which are on offer but still not bad for a 12 pack. works out 19p per tin.
