Before the discovery of the balloon, it was thought that the only essentials for a party were friendly guests and a CD of whale screams. Get ready for a modern get-together with today's Groupon: for $10, you get $20 worth of party supplies and accessories at Jeannie's Let's Celebrate on Canfield Avenue.

Jeannie's Let's Celebrate fosters one-of-a-kind fiestas with a panoply of party supplies and custom decorations. The shop specializes in balloon design, transforming helium globes into arches ($15.99) or a daisy pillar with a blossoming pink flower resting atop a lime-green stalk ($19.99). Ground airborne elements with a handmade centerpiece ($19.99+) or a plastic tablecloth ($1) from a spectrum of shades as polychromatic as a rainbow shooting through a paintball course. Jeannie's also shelters every-occasion cards ($0.59 each), invitations, plates, napkins, and décor until they are adopted into party-happy abodes.
