At Christmas - Season 1

Behind the scenes at the supermarket in the run-up to Christmas, from the technology behind recyclable wrapping paper to the making of the Christmas advert. However, Key suppliers are feeling the financial squeeze, new products fail on the production line, and a snap frost dents the grape harvest.

Meanwhile, store manager Lee faces the daunting challenge of opening the company's 986th store during a bleak mid-winter of rising costs.
