Attics should be reserved for storing unwanted siblings and Grandpa's Victorian dust collection. Put excess belongings where they belong with today's Groupon: for $25, you get $75 worth of self-storage at Your Extra Storage. This deal is valid at three locations in the Knoxville area: Cedar Bluff, Powell, and Halls.

Your Extra Storage offers a multitude of multifaceted storage spaces available in three secure complexes. Indefatigable fans keep all climate-controlled units between 60 and 78 degrees year-round, with each unit individually ducted and inspected by a discerning staff to ensure that hoards of chocolate and fondue fuel remain palatable for months at a time. Climate-controlled receptacles start at $62 a month for a 5'x10' unit and go up to $185 per month for a voluminous 10'x20' space. Traditional self-storage starts at $30 a month for a 5'x5' space that will nicely accommodate a large collection of miniature sofa chairs, while a 10'x15' unit for $105 a month can store full-scale furniture models. Customers seeking safe harbor for out-of-season RVs can park their vehicles in a secure open-air lot for $40 a month.

In addition to the convenience of its units, Your Extra Storage also provides an advanced security system comprising fully fenced and lighted perimeters and digitally controlled gates, which each tenant can access with a code during staffed hours. Month-to-month lease contracts ensure that customers are not stuck with empty storage space after removing their belongings or finding a more suitable living situation. Boxes, tape, and locks are also sold on-site for packing purposes and last-minute Houdini encounters.

Although Your Extra Storage sometimes features a discounted price online, this Groupon still offers the best deal available.
