60% of shoppers abandoned a brand they had been loyal to this year after price increases, and 70% said they are less loyal than a year ago, according to DOSS research.
A 16% price jump marks the main breaking point, with groceries hit first as 76% switched brands there and many moved to generics, private labels or cheaper national brands.
Discount chains, dollar stores and warehouse clubs gained the most shoppers, while traditional supermarkets and mass retailers lost the most as consumers traded down.
37% of AI users in an Accenture survey said they would let a digital agent steer them to a different brand, adding a second pressure on loyalty beyond sticker shock.
