Hey, we’ve all done some pretty stupid things after one too many drinks. But new research out of the US has shown pissed people with a credit card are a boon for retailers and, unsurprisingly, fast food restaurants.

According to the study by Finder.com, Americans spent $US39.4 billion ($A55 billion) on spontaneous drunken purchases in 2018. That’s up almost $US10 billion from the previous year.

According to Finder’s maths, 26 per cent of respondents to the survey admitted to a drunk purchase in the previous 12 months. If you extend that to the US’ population, it works out to 53.4 million pissed shoppers spending an average drunken amount of $US736.

Drunk men spend more than women, averaging $US870 a year. Gen Ys averaged $1047, the Xers $469 and Baby Boomers at $466.

In 2017, the average drunk spend was $206, while last year it climbed to $448.

And what do drunk shoppers buy? Some 52 per cent of respondents admitted they’d lashed out on a take-away meal. A further 43 per cent had bought shoes and clothing, while 30 per cent had bought cigarettes.

Even better, 14 per cent admitted to having booked a holiday after one too many vinos and a staggering 10 per cent had purchased a car!
