well if that isn't the fastest $50 i've ever donated...what a great idea :)

It is a great idea and supporting a good cause! However, does it sound like you have to open a store with them to be eligible?

No, that's one of several options to earn entries. You can just donate to St. Jude.

Hate to be that guy but what's the environmental impact of flying folks to orbit "just for kicks" if this were to become a business

Depends a lot on the fuel used. Solid boosters are terrible. Kerosene, like on the Falcon not too bad, but not great. Methane is better, it can in theory be made carbon neutral. Hydrogen is the best because it only produces water, but it’s not great as a first stage.

Per capita, a lot. In absolute terms, effectively zero.

Do you know roughly how many "car-hours" this flight would be in terms of green house emissions?

Not car-hours, but a Falcon 9 launch apparently has similar impact to a 777 crossing the Atlantic. Not nothing, but surprisingly little all things considered.
