Was just at my local Tesco in Cambridge and they had stocked up on a new yoghurt brand called Yoo. The introductory prices are very good deals indeed. I suspect that this would be likely other large Tescos as well, tho I never see introductory prices at my local Tesco in London Old Kent Road.
Flavours are: strawberry, rhubarb, fudge, raspberry and vanilla.
4 singular pots (good size, larger than Activia pots) for £1.00
4 corner pots (with fruit jam or chocolate bits) for £1.00
or £1.50 for the package of 8 pots!
Here is an article for Yoo and Tesco! http://popsop.com/44410
