That or they should do a kickstarter type deal where they flat out tell you, "Give us money, you're buying into our dream, you're funding our startup, when/if we make money you'll get a bigger kickback than regular Joe retail, also we'll give you a BA shirt that you can either wear with pride or wear with a sense of irony depending on how things shake out. We may soar, or we may crash and burn, but now you know."
