Is it okay to use expired sweetened condensed milk?

I want to make fondant for a cake, but we only have sweetened condensed milk that expired April 11, 2011. I really hate using expired things so I don't know if I should use it or not?
Thank you!
Update: I don't live close to any stores where it won't be like 3 times as expensive as it should be. I'll probably use it if it looks normal. Thanks.
