Inside the Supermarket - Season 1

It's the company's 150th anniversary, but facing intense competition from Lidl and Aldi, Sainsbury's is considering merging with Asda.

Finding that customers are returning all their single-use food packaging to stores, Sainsbury's trial a recyclable alternative to the plastic bags used for fruit and vegetables.

Sainsbury's plan a special party to celebrate their 150th year with a very special guest.

Sainsbury's stores try to cash in on the increasing number of Brits holidaying in the UK, but in Penzance the fridges break down on one of the hottest days of the year.

Sainsbury's embarks on an ambitious makeover of its store in Hedge End, Southampton, with manager Becky and her team eager not to lose precious custom while the refurbishment takes place. At head office, two new food brands - a chorizo snack and a fresh fruit tea - are being trialled across 70 stores, while in retail, plans are under way for this year's Christmas campaign.

Halloween presents one of the last big sales opportunities of the year, so the pressure is on Emma and Martin from the produce team, battling the wet weather to ensure this year's pumpkin crop will deliver the one million required for stores around the country. In the Locksbottom branch in Kent, Halloween could end up being a bit of a nightmare. The store has a low customer satisfaction rating, so manager Mij is on a mission to retrain and re-invigorate his young team in preparation for the big pumpkin push. Meanwhile, Laura and Donna from the communications team head to Romania for the filming of Sainsbury's Dickensian-themed Christmas advert. How will it stand up against the commercials produced by their rivals?
