If you don't think you'll go through all 7 gallons of milk, can you get some of the shelf-stable stuff, like Parmalat?
Also, if you make lentil soup or split pea soup with the dried beans, you don't need to worry about soaking them overnight first. You can get onions, celery, and carrots to add to the soup and freeze the extras. You can make a lb of dried beans go pretty far if you need to.
