NEW YORK (AP) — Shoppers buoyed by solid hiring, healthy pay gains and substantial savings are returning to stores and splurging on all types of items. But the big question is how much will supply shortages, higher prices and staffing issues dampen shoppers’ mood this holiday season. Shoppers, already fatigued with pandemic-induced social distancing policies and other setbacks, may get grumpy if they can’t find the help they need at the stores, or can’t find their top choice item. They may also be disappointed by some of the skimpy holiday discounts. Still, don’t write off the resilience of shoppers who have shown signs they want to celebrate the holidays after muted celebrations last year.
