Before the invention of candy, mankind had to make do with "nature's candy"—fermented cabbage, fruit the monkeys didn't want, and live, feather-covered Peeps. Celebrate man's triumph over nature and decorate your mouth for Halloween early with today's Groupon: for $5, you get $10 worth of nostalgic candies and more at Sweetness, a candy and sweet boutique in La Grange.

Encyclopedic in its generational stock of goodies, Sweetness satiates sweet teeth with row after row of throwback bounties. From Pop Rocks ($0.95), to Charleston Chews ($1.25), to a wide variety of PEZ dispensers ($2.25), the shop stocks edible memories for all ages and personality types. Uninhibited hands can hoard individual items such as theater-sized boxes of Raisinets and Lemonheads ($2.25 each), while foresighted foragers shovel sweets such as Atomic Fireballs, Smarties, and Jolly Ranchers ($5.25/lb.), as well as Gummis in the chewable form of bears, berries, butterflies, and marmocoons ($3.25–$4.25/lb.). Sweetness’ creative candymen can also create custom-poured chocolates. No matter what sticks to the palm, a single swing through Sweetness can easily fill the heart, stomach, and pillowcase of any autumn enthusiast.
