I've just read this thread and have been on the Slim & Save site and ordered a month's supply. Different tastes and something different to try and look forward to keep you going, so rather than fail (AGAIN!!!!), I thought I'd mix and match.
By the way, I have had nothing but excellent service from Exante. I have always had my order on time, always been replied to and once when I made a complaint got very well compensated. I won't be abandoning Exante, but mixing things up a bit.
