Tipster eliter1 has pointed me in the direction of another discount provided by GetGlue in their partnership with Food Network! This one is actually twofold. If you head over to The Next Iron Chef, Chopped, Ace of Cakes, Iron Chef America, or Good Eats, you'll be presented with an offer for a fandom discount of up to 10% off at the Food Network store.
The discount maxes at 10% regardless of whether you're a Fan or Superfan, but either way it's still a nice "thank you" for the fans of the shows.
The second discount is provided by any other Food Network show. The pages for other shows will provide you with an offer for free shipping on an order of $79 or more.
While the $79 minimum may seem a bit high, you have to remember that a lot of the items in Food Network's online store are high-end cookware and are not light in the weight department, so free shipping is a blessing in that case. Thanks to GetGlue and Food Network for the discounts!
