Valentines Day arrives this weekend with a wintry mix of obligation and indifference. If you’re one of those romantics who find it necessary to venture outdoors and try to look handsome/beautiful for a  significant other during days there’s a forecast high of 19 degrees Fahrenheit and a low of -4 (this is not a joke), here are some suggestions on ways to pass the time between shivers. Prices range from free to I-can-afford-to-live-in-Cambridge:

Products

UnReal, which makes less guilt-inducing versions of popular candy products, is selling limited edition Valentines-themed tins and bags of its red candy coated milk chocolate “gems” (think of M&Ms made with organic cacao and dairy, no artificial ingredients, and colored with beetroot juice) or dark-chocolate peanut butter cups at the Whole Foods Cambridge stores at Fresh Pond, Alewife Brook Pkwy and River Street. The candies are $5 or $10. Buying a “double dozen” roses and a tin of its “Unreal Love” branded candies is $30.
