Florist shops are already in overdrive, with several owners saying they were too busy for an interview. Others reported an uptick in pre-sales this year because Valentine’s falls on a Thursday. “Valentine’s Day is usually a day-of kind of holiday, but since it’s on a Thursday people have all week to prepare,” said Rebecca Fitzgerald, who owns Forget Me Not Florist in Northampton. To prepare, Fitzgerald ordered 67 cases of flowers for her two stores at 1 Roundhouse Plaza and in Thornes Marketplace, only to have last weekend’s snowstorm delay their delivery until Monday.
