Other than sporting a constant tan, the best way to trick yourself into thinking it's perpetually summertime is to tattoo sunglasses on everyone's faces. Make summer eternal the easy way with today's Groupon: for $10, you get $25 worth of tanning services at Premiere Tan. This Groupon is valid at Premiere Tan's four locations in Evansville and one location in Newburgh.

The tan techs at Premiere Tan add golden accents to skin using an echelon of German-made Ergoline beds and UV-free Mystic Tan systems. Beds ranging from Levels 1–5 allow patrons to customize their glows, and on-board ventilation systems allow guests to bask in cool, moving air. Ergonomic contouring and MP3 players in some beds conjure up comfort beneath 32 full-body lamps or high-pressure systems in higher-level units, which may yield longer tans. Patrons prep for visits to friends stuck in sand castles with single sessions (prices vary) or monthly memberships ($23.88+/month).

Mystic Tan sunless tanning ($19.95) bronzes hides according to preselected specifications in automated booths. A mist of DHA bestows a sun-kissed look, and a blend of aloe, green tea, and açaí protects the integrity of precious skin cells. The entire process takes five minutes, and the resulting tan, like a staring contest with the family parakeet, can last several days.
