The Australian supplement company Tribeca is one of the few international brands exhibiting at this week’s Stack3d Pro Expo. Like most it has a number of attractive features on its booth including a solid sitewide sale of 30% off with the coupon code “STACK3D”, as well as a fairly worthwhile giveaway. The prize up for grabs for everyone is a year’s supply of Tribeca’s flagship formula, Green Tea X50. All you need to do to get in the draw for the massive prize is purchase anything from the brand’s UK, US, or Australian websites, and you’re in to win.
