Got more Halloween candy than you know what to do with? You can take it to any Magic Beans store for its annual candy buy-back through next Monday. Bring in at least 1 pound of trick-or-treat leftovers and get 20 percent off any one full-priced toy. (The discount must be used the same day.) The candy will be donated to the Brookline Emergency Food Pantry, the Centre Street Food Pantry in Newton, Operation Gratitude (for US troops), and www.soldierscarepackages.com.
