Dragons’ Den’s Peter Jones is celebrating after securing a deal with Sainsbury’s to stock his latest investment, The Little Bag of Bags.Those of you quick enough to catch Peter’s rather less successful show Tycoon before ITV culled it from prime time might remember founder Justin Chieffo’s idea for storing and re-using carrier bags.A small fabric bag made from Fairtrade certified cotton, it has an elasticated opening at one end and a hanging loop at the other to hook onto shopping trollies or around the home.Having already helped The Little Bag of Bags into Tesco stores, Peter sealed a deal with Sainsbury’s after face-to-face talks with chief executive Justin King. Who was it that said 'it’s not what you know, but who you know?'“I am very proud of the achievements of Justin and Michelle (co-founder). Their business is really taking off, which is great to see,” said Jones, announcing the deal due to start next week.Funny then, that Justin didn’t even make the final of Tycoon. Just goes to show what makes good business sense doesn’t necessarily make great TV.
