Again, no April Fool's joke, Seattleites... when you become a fan of Cupcake Royale on Facebook, you'll get a coupon for a free lemon mascarpone cupcake w/coffee purchase. Once you're a fan, go to their Wall Photos and it's #63 of 64, or just scroll down their wall until you see the coupon thumbnail. Then print that sucker off and use it before April 4!
I do know some cupcake-lovers who are non-coffee-drinkers, so hopefully they'll be cool about letting you substitute tea, a carton of milk, etc. for that coffee.
