Did you purchase your MacBook with a major credit card? Because, if so, that may effectively double the manufacturer's warranty. I know with AmEx it does (and I thought most Visa and Master Card's as well). It won't allow you to purchase AppleCare at this point, but will give you another year (or, at this point, 8 months) of security.
You should also look into what may be covered under your renter's or home owner's insurance.
I never buy AppleCare. I make major electronic purchases with my AmEx card (which I pay off immediately, of course), so that the manufacturer warranty is doubled. Typically, I don't keep a computer longer than 1.5-2 years...and if I do, it's highly unlikely that a manufacturing defect will manifest itself after two years. And my home owners insurance covers anything I may accidentally do to it (which is never covered by AppleCare).
