Halloween is the perfect time to dress incognito, watch scary movies, and hand out stockpiled prunes. Celebrate the best parts of All Hallows’ Eve with today's Groupon: for $10, you get $20 worth of Halloween costumes at Halloween Costume Warehouse's seven Phoenix locations.

Halloween Costume Warehouse outfits revelers in spooky, adorable, or sassy duds for men, women, kids, and infants. The selection of thrilling threads ($9.99–$129.99) varies from location to location, but recent offerings for tots have included the baby cuddly lion ($14.99 on sale), a plush lion jumpsuit that can help babies rule over animal crackers. Young trick-or-treat warriors can bravely battle terrifying doorsteps in the guise of Captain America complete with a shiny blue jumpsuit and mask ($19.99), or they can charm ghouls in a frilly red Elmo dress ($24.99). A wide selection of adult attire runs the gamut from alluring burlesque ensembles to hair-raising costumes of high-school trigonometry teachers.
