Ginny Rich found the Burberry jacket and thought she was about to snap up a bargain, until she checked the price tag and realised that wasn't quite what was on offer.
To her amazement, the luxury coat was priced at £499 ($650) - and although it was labelled as 'brand new', the tags were missing.
Ginny, 46, shared her picture online, sparking comments from locals who said prices at the charity store in Princetown, Devon, were 'over the top'.
She said: "I know Burberry coats can cost £1,000 new but when we saw it we were laughing. The coat didn't even look new - and it didn't have any labels.
"Charity shops are for the kind of people who can't afford to buy a new coat - and if you were a millionaire who can afford a designer label, you wouldn't go into a charity shop - you'd want the most up-to-date fashion.
"I just don't think the prices in Oxfam add up; this is Tavistock, not London or Oxford. You go in some days and can find something for £2.99 but on other days you might see something that costs less new at Primark. There just doesn't seem to be a balance with Oxfam."
Other items in the shop included another Burberry jacket on sale for £329 ($429), which was also labelled as brand new. A retail assistant from a nearby Oxfam shop responded to the picture online.
They said: "We very kindly get sent clothing from brands like this and price them at a third of their retail value - a bargain for those who would like brand new designer stuff and an amazing contribution to help people."
Another volunteer for Oxfam wrote: "It is a cashmere jacket. Check online and see what its retail price is. It is such a bargain [sic]."
But others weren't so quick to see the silver lining, and pointed out that the price was extremely high compared to standard charity shop prices.
One local resident said: "Oxfam prices are getting ridiculous. I used to love it but go to the other shops now," while another added: "Oxfam are getting greedy. Maybe if they want those prices they need to sell on an auction site. Clothing donation[s] whether designer label or not, will not get £329 in Tavy."
A spokesperson for Oxfam said: "We maximise the money we raise from donations by selling them at a fair price. Our volunteers are trained in pricing so people can be assured not a penny of their donation goes to waste.
"We work hard to raise as much money as possible from the items given to us to support our work fighting poverty around the world."Featured Image Credit: SWNS
