While Bay Staters may have very few places to go for basic last-minute shopping, there are still some convenient stores and smaller markets open.

What is open on Thanksgiving:

CVS

While you probably won’t find a whole turkey at your local pharmacy, CVS is known to carry some staples. If you forget the gravy mix or some butter, CVS will be open on Thanksgiving, but hours may vary by location.

Walgreens

Like CVS, Walgreens also has some of the most basic groceries and drinks. Most Walgreens stores will be open on Thanksgiving from 9 a.m. to 6 p.m. to meet short-term grocery or healthcare needs.

H Mart

H Mart – a national Asian supermarket chain with locations in Quincy, Burlington and Cambridge – is open 365 days a year, including Thanksgiving.

South End Food Emporium

South End Food Emporium is a neighborhood market located at 469 Columbus Ave. in Boston. It offers fresh fruits and vegetables, meats, cheeses, crackers and everyday groceries. For snacks, appetizers or basic ingredients, Boston area residents can shop there on Thanksgiving from 7 a.m. to 8 p.m.
