People go way too overboard on this 'freshness' stuff and I have bought a lot of great film at barn sale prices because of it. As soon as someone sees it's 1 month out of date they start to think that it will turn to mush right in front of their eyes or something. While it is technically true that freezing film does slow the degradation process of the chemicals in the emulsion, you can shoot b&w film years and years out of date when it's stored in average temperatures and it will be perfectly fine. I e-mailed AGFA about this last year and they told me the same thing. Forget this freezer stuff unless you're thinking of keeping the film for 10 years or so. Honestly, I have film that is a lot older than 10 years and it's fine.
One of my past times is wondering into old-style camera stores and seeing a box or out of date Plus-X sheet film (usually 4x5) and asking to see it. I handle it, turn it around and with some sadness tell the owner too bad, it's out of date. I can usually get it for about $20 or $25 and I reluctantly take and say "I'll give it a try".
So l relax, your film is fine and will be for years to come. The only way to ruin it is to take pictures of misty harbors and small children.
