A fraudster was jailed for 20 weeks after getting repeated refunds on items he bought from high street stores.
Jobless Richard Jenkinson also stole goods and returned them to be given gift cards instead of cash - which he sold on the internet, a court heard.
District Judge Joanne Alderson told him: “These are deliberate, pre-planned sophisticated frauds which only stopped when you were caught.”
Because of the prison term, she ordered no compensation from Jenkinson, 36, of Brewster Close, Swanwick.
Peter Bettany, prosecuting, said he targeted Boots who had a policy of handing out gift cards when customers returned items without receipts. He received £242 when he sold a gift card worth £295.
Jenkinson had previously been arrested for shoplifting in Nottingham branch of the company and also at Meadowhall.
Faz Sadiq, mitigating, said Jenkinson suffered from bi-polar disorder which caused mood swings, prompting him to sell the cards for less than their face value.
Jenkinson admitted dishonestly seeking a £139 cash refund at Heanor on January 23; having and transferring criminal property.
