I don't know much about how godaddy auctions work but I found a cheap PR 4 domain, it only has 9 links. It's 3 years old, I never really buy and sell domains. Would it be worth it to buy it and resell it for more? How much do PR 4's usually sell for? Could it be that it's a PR 4 now but because it expired after the last PR update that it could drop to 0 soon? I see this sometimes and not sure if they're worth it or not.
