Well, I hate to be a party pooper, but I've been pretty unhappy with one aspect of the greenpoints "experience." When you buy from a merchant, and all items are not immediately available, multiple shipments may be made. In that case, the greenpoints awarded for part 2 over-write the greenpoints for part 1; part 3 over-writes part 2, etc. I've explained this to them repeatedly, in numerous e-mails and phone calls. One instance they fixed, the others they have not -- YET. They claim that I am the only person on the planet experiencing this problem.
