The Walmart in Summerville is always so busy! It doesn't matter if you go to the one by 26 or on Dorchester, but both Walmart's are constantly busy. Maybe that is becasue you can't beat their prices on many things. We routinely get a lot of groceries from there and you cannot beat their price at all on anything. They will even price match to the other grocery store if you show them the other grocery's circular. I think it is easier to get in and out of the Dorchester store (as far as traffic and checkout) rather than the one by 26 but they are both about equal. The Dorchester store is newer with some self checkouts & that helps. They have a great garden center.
