Manor Bakeries is running a £1.5m Cadbury's Mini Rolls in-pack promotion targeting the lucrative lunchbox market. It begins in mid August and builds on last year's promotion ­ a free safe' in every six pack. This year's version also offers the chance to catch the safecracker hidden in special gold safes and win one of 1,000 prizes which include MiniDisc players, pocket TVs and calculators. The promotion is supported by TV ads from September 4. Manor category manager Eric Craig said the safes made the mini rolls more portable for lunchboxes. {{P&P }}
