A customer to the shop causes Granville to discover there is a gap in the shop's security, which prompts him to take measures to plug it. Meanwhile, Gastric has taken a liking to the cooking of a nearby neighbour, prompting Granville to find a way to tempt him back to Madge using a cherry picker and some of Mavis' home cooking.

Granville is eager to go on a double date with Mavis and Madge, but needs to smarten up Gastric, which soon proves a handful when his only suit gets ruined. Meanwhile, Mrs. Featherstone decides to use Mr. Newbold to help her discreetly woo Granville, while Eric and Cyril find themselves swayed by the shop's newest beauty product - from North Korea.

Granville buys a large display item to inject a little bit of sunshine into shop life on the day of Kevin's wedding. However, Kevin is the world's most reluctant bridegroom and is still having second thoughts. Can Granville ensure he makes it to the ceremony this time? The wedding spirit has also rekindled Mrs Featherstone's desire for a fourth husband, and she is training her formidable sights on either Granville or Mr Newbold.

Granville's scheme to sell salami as an erotically charged new product called Yaggis is in danger as a customer's husband returns seeking redress. Cyril and Eric need advice on how to impress their wives, Mrs Featherstone's plan to snare Mr Newbold as a fourth husband is not going well, and Granville has to quickly sell some damaged tins of chilli beans.
