I'm sure I read somewhere a while ago they were changing bar supplier. Not sure though, the shake packs have been slightly redesigned as well from when I first got them so maybe everything is changing?
Has anyone else used the Tesco Ultra Slim meal replacement bars in an emergency? I did last time I did a VLCD and I think Exante had said they were similar enough not to mess the diet up! Sometimes I forget to bring food if I'm out for the day and there always seems to be a Tesco close enough to help me out. (They're half choc coated but no raisins beaky!)
