Studies show that children who are exposed to stimulating toys at a young age are less likely to join their neighborhood's roving group of postal workers or get caught smoking old copies of The Economist. Keep childhood wholesome with today’s Groupon: for $15, you get $30 worth of toys from Discovery Toys online.

Discovery Toys is an expansive oasis of mind-bolstering toys, games, and hard-to-categorize playthings, all of which are meticulously catalogued according to age appropriateness, learning function, and resistance to blowtorches. Baby geniuses and infant intellectuals will be even smarter after experimenting with toy tools that develop motor skills and thinking skills, such as the colorfully transparent, bead-loaded rainfall rattle ($12.50). Preschoolers can omnisciently preside over miniature worlds such as the PlayTown school or PlayTown pet hospital ($35 each), while school-age kids can ditch fads, such as deriving nutrients from food, in favor of heavy-duty diversions, including the light-up, compass-included star-explorer kit ($27.50).

Discovery Toys’ inventory inherently encourages hands-on, brain-heavy interaction, and many of its items are fun for kids and parents to puzzle over together. Their high quality and safety standards spare customers the hassle of recalls of possessed, expletive-spewing dolls. Beat the buzzer on holiday shopping and gift some intelligent diversions to a deserving miniature human with today's Groupon to Discovery Toys.
