One in five people plan to sell unwanted Christmas presents online, with jumpers, shirts, CDs and books topping the list, according to new research.
A study of 7,000 adults by magazine subscriptions website magazinesbymail.net showed that people in the West Midlands were most likely to sell unwanted gifts online, while those in Scotland were least likely.
Younger people sold most items via the internet, while over 55-year-olds were least likely to dispose of presents in this way, the study found.
Nicola Rowe of magazinesbymail.net said: "Sadly not all gifts were gratefully received this Christmas, with many of us now heading to our PCs to place unwanted Christmas presents on online auction sites, rather than leaving them to gather dust at the back of a cupboard.
"From CDs and DVDs that don't fit people's musical tastes, to vases that just don't match the decor, millions of gifts are already being repackaged for sale online."
