I'm not sure if this is a country-wide thing, but yesterday I stopped in at my Electronics Boutique in Pleasanton, California and discovered that they're currently doing a Guild Wars promotional event. Essentially, EB is currently selling pre-orders (which include promotional items and early access) for a grand total of one cent!
Essentially, people that go to the store near my home can now try the game practically risk-free. While I can't guarantee that the same will be true for everyone, I would certainly suggest heading over to EB if you're still looking for keys for yourself or for hooking the thirty friends you weren't able to earlier.
