Like an eccentric uncle, the holidays often sneak up on people and leave tinsel wherever they go. Deck the halls with today's Groupon: for $140, you get up to 75 feet of custom Christmas lights installation from The Service Group (a $300 value). For a list of zip codes the illuminators will service, click here.

The Service Group's exterior outfitters decorate homes with commercial-grade Christmas lights that are cut and strung to accent each house's unique architecture. Façade highlighters beautify homes by draping windows, bushes, and doors in soft illumination and by equipping rooftops with glowing lines for easy reindeer parking. The Service Group fully insures installations and includes a configurable timer that automatically rests lights during the day and awakens them at night. Staffers maintain light fixtures throughout the holidays, and as the sun dawns on a new year, return to residences to whisk away the blinking bulbs and compare favorite Christmas presents.
