The woman said she left her wallet in her shopping cart and noticed it was missing when she went to pay for her groceries around 2 p.m., police said.
The $20 wallet contained credit and debit cards, $150 cash and a spare key to her car, she told police.
In the time it took to begin canceling her credit cards, the thief had already made a $2,800 purchase at Best Buy and attempted to spend $2,950 at an Apple store, police said.
The theft could be connected to others at Stop & Shop and Whole Foods locations in Fairfield and Westport over the past few months, police said.
