Klarna users have been issued a two-week warning as up to £10 fees are set to be introduced for those who miss a payment.
The 'buy now, pay later' service allows people to purchase online items with money from Klarna rather than their own bank. They can then pay Klarna back after the fact, making it handy when money is getting a bit tight in the run-up to payday.
The service asks that users pay the sum back in a set timeframe, but currently do not issue late penalty fees. However, this will change in the UK from March 16.
