Merle Brown, a 53-year-old writer from Scotland, buys most of her gifts secondhand. ¡°I love the thrill of finding something unique and special that I can¡¯t get anywhere else,¡± she says.

She looks for vintage glass and kitchenware, Christmas cards and puzzles ¡ª all things unavailable in conventional stores. This Christmas, about half of the gifts she¡¯s purchased so far have come from thrift stores run by U.K. charities. The trend is catching on across the globe.

Gifting secondhand used to have a bad rap (think last year¡¯s candle or dusty bath set), but it doesn¡¯t carry the taboo it once did. In the U.K., some 84% of people say they plan to buy at least one pre-owned Christmas gift this year, according to research by the resale app Vinted and the market researcher Retail Economics. In the U.S., 3 in 4 people believe secondhand gifting has become more socially acceptable over the past year, according to a survey by the resale app OfferUp. The British Heart Foundation charity ¡ª with 680 secondhand shops in the U.K. ¡ª says demand has surged.
