Virtual cards : Cinco de Mayo

The 5th of May, otherwise known to margarita-lovers as Cinco de Mayo, celebrates an important day in Mexican history. But for Americans, it's often an excuse to throw a Mexican-themed party. Before whipping out the taco dip and the sombreros, be sure to kick off the Cinco de Mayo festivities by sending your amigos a Cinco de Mayo card! (Tip: You can also use them as invites to your fiesta!)
