If anyone plans a group buy in the future.

Why couldn't everybody just paypal their money to a central buyer, and then that buyer buy the thing? That's pretty much exactly what that site is, I don't know why you need a separate site to paypal money.
So that they cannot run off with the money. :awesome:

As long as you have a trustworthy person, not an issue.
Who says they can't run with the money with this thing? It just paypals money to the moneykeeper from the moneygivers.
