Redbook US same-store sales rose by 9.6% from a year earlier in the week ended May 9 after a 7.8% year-over-year increase in the previous week.
Redbook noted higher sales of seasonal products including clothing, footwear and outdoor goods due to rising temperature and graduation sales.
Mother's Day also boosted sales of gifts items including cosmetics, jewelry, cards, flowers and small appliances. However, annual growth was unaffected because Mother's Day occurred during the same period as last year.
Through the first selling week for May, sales were up 9.6% compared with May 2025, well above the target for an 8.6% gain, Redbook said.
