Almost half of Britons have shopped online after drinking, often falling asleep or having to abandon a transaction, new research shows.
In a survey of more than 4,200 consumers, 14% admitted they would never have made their purchase if they had been sober, often sending goods back straight away.
The most popular items bought online by "boozy" shoppers were clothes and shoes, DVDs, books, video games, technology and lingerie.
Shopping comparison website Kelkoo said its poll showed that more than half of online shoppers spent more if they were tipsy.
Most drink-fuelled shopping is done between 11pm and 1am, although one in five makes purchases up to 5am, the survey showed.
Chris Simpson, of Kelkoo, said: "Online shopping has become a daily part of Brits' lives and people are taking advantage of being able to shop at any time of the day, whether at home in bed, on the move, or in bars and restaurants.
"Our research shows that while people shopping under the influence of alcohol could spell good news for those on the receiving end of gifts, we'd always advise shoppers to think carefully when making purchases and remember that they are able to use retailers' returns policies if they realise afterwards that they've purchased unwanted items."
