Actually, it really was $0.99 for a short while. Here's what the admin said:
Hello everyone, i am the owner of the site, and i see ALOT of you (about 75 of you) have purchased domains. I did not know it would get this popular. Everything is real, untill i reached my limit. Im sorry, but the domains will remain normal prices until somtime next month. They will be .99 for 2 hours every month.
