The expiration dates are going to be constantly changing as this product is still in production. The last time I bought it I think it was good until at least mid-late 2014. If you do get a pack and you are worried you won't be able to use it before expiration date it's always best to refrigerate the film. I try to refrigerate all my film regardless of when i'm going to use it, just make sure you seal it up tightly to prevent any moisture. Once ready to use let the film sit out unopened for several hours to ensure you don't develop any condensation from the temperature change.
Hope that helps!
