I was delighted a couple of years back to find that Kellogg's Start had re-emerged onto the supermarket shelves after what seemed like 15 years away. It was my favourite breakfast cereal as a boy and it still is!
Sadly only Sainsburys and Tesco seem to stock it (certainly my local Waitrose doesn't) so we have to make occasional special trips, just to pick up an armful of the stuff. It's been on special offer recently, so that's a bonus 🙂
Why it ever went away is a complete mystery to me.
