Before bottled fragrances became available, humans perfumed their bodies by rolling in meadows of honeysuckle or lining their sweaters with scratch-and-sniff stickers. Explore a contemporary aroma ritual with today's Groupon: for $10, you get $20 worth of Makes Scents’ line of custom-blended perfume oils, designer-inspired perfume oils, and scentable products at Makes Scents.

The staff at Makes Scents concocts signature smells that stock a pantry of more than 100 total original perfume oils ($8 per 1/8 oz.) and designer-inspired perfume oils ($10 per 1/8 oz.). Make an olfactory impression on a loved one with scents such as chocolate, rose, and Vera Wang, or waft a snout-tickling hint to unkempt neighbors with a 2-ounce spritzer of fresh-cut grass ($18). Compose a completely individual scent score by layering paraben-free bath salts ($6–$7.50) or aloe-vera moisturizer with safflower and avocado oils ($3.75–$23) or by slathering a bass guitar with peanut butter and thrashing away. The diffusion reeds ($10–$25) snag the nose's attention while freshening odiferous space or the unscented blends allow customers to freshen up without antagonizing allergies.
