A 20th birthday party was held for the Peterborough British Heart Foundation.
Staff and shop volunteers celebrated with tea and cake while certificates were awarded to people who have been volunteering at the shop for more than a year.
Jacqui Whitehall, area manager of the BHF, in Bridge Street, said: “We’ve enjoyed a fantastic 20 years of business in the Peterborough shop.
“I’d like to take this opportunity to thank all our loyal customers and volunteers who really make this shop special and help the BHF fund its life-saving research.
“We’re always in need of stock, so if you’re having a clear out join the fight for every heartbeat today and help fund life-saving research with your donations.”
