NEW YORK A record amount of price-pinched holiday shoppers are expected to use buy now, pay later services for Cyber Monday to relieve stress on their wallets, according to Adobe Analytics.

Shoppers are slated to spend between $12 billion and $12.4 billion online on Monday, with $782 million of purchases made with BNPL services, including Klarna and Affirm, representing a surge of nearly 19% fr om last year, the data company said.

While BNPL has consistently been growing in popularity over the past several years, its usage is getting a further boost from budget-conscious shoppers trying to avoid the additional fees and interest that come with purchases made through credit cards.

Economists anticipated the holiday season would be slower than recent years due to economic pressure on consumers who are dealing with higher interest rates and lingering inflation.

A survey by Klarna found nearly half of those surveyed worried that they would not be able to pay off credit card bills in full from holiday spending.

The buy now, pay later firm saw a 29% increase in orders placed by U.S. shoppers, with some of the most popular items being personal electronics, televisions and kitchen appliances.

"The scale of the adoption (of BNPL) has just gotten so big. It's become really, really, really popular," said Dan Dolev, an analyst at Mizuho Securities.

Affirm shares surged 11% on Monday after Adobe Analytics released the upbeat BNPL data.

Average basket sizes for buy now, pay later orders on Black Friday declined 32% compared to last year, according to a report from Quantum Metric, a sign that shoppers aren't making as big of purchases this year.
