Ancient Egyptians often threw salt up to the heavens to bring rain, which is why modern humans throw pepper at vending machines to summon Diet Coke. Enjoy a showering of seasonings with today's Groupon: for $30, you get a six-month membership to the Hot Sauce of the Month club from Pendery's World of Chiles & Spices (a $60 value).

Founded as a spice trader that made deliveries via horse-drawn stagecoach in 1870, Pendery's World of Chiles & Spices continues to stock customers with many flavors of tongue-searing hot sauces. Club members receive one bottle each month from Pendery's exhaustive list of liquid pyrotechnics, each bearing fear-inducing names such as Fire Ant Juice, Liquid Napalm, and Satan's Blood. Use tongs to apply a 5-ounce bottle of Bubba's Green Fire, a 2010 Fiery Food Challenge winner, or keep a bottle of Pure Cap 500K in bed for warmth during the winter months. Pendery's fiery taste technicians also weave innovative flavors into the potent recipes, crafting bottles flecked with peaches and vidalia onions, and steeping the Blair Q jalapeño-wasabi sauce with ginger and tomatillos. Though not included in today's deal, Pendery's also proffers a collection of fresh chilies, spice blends, and containers to store the ashes of old love letters.
