try the fridge at work?
I had an 'overstock' issue earlier this year, when the freezer actually was full of food, and someone gave me a ton of frozen paper, and at the time winter was hopping up and below 0C.
I put the overstock in the freezer section of my workplace fridge in well wrapped plastic bags. A month or two of eating the frozen foods, and compacting half full boxes of grade 2, and grade 3 paper of the same vendor in different envelopes, and testing and tossing the seriously fogged stuff, and I was able to bring the office stored stuff home.
Maybe see if you can strike a deal with the local convenience store etc, if you don't have acces to a workplace fridge.
