Do you buy shredded cheese?  Instead, buy the “block” cheese and shred yourself.  Put it in a plastic bag.  You can also watch for the shredded cheese blends on sale, then stock up. Most cheeses freeze quite well.  I usually purchase my shredded cheeses at the club store in bulk, repackage into smaller freezer bags, and take them out when I need them.  When the grocery stores put the smaller packages of blended cheeses on sale for $1 I buy several packages of each of my favorite blends and pop them into the freezer as well.  I also buy the large blocks of cheese and freeze half so I don’t end up throwing moldy cheese away.  Just look at the price per pound for the cheese you buy.  Unless the shredded cheese is on sale, the convenience is very expensive.  You can also save by avoiding the pre-sliced cheese.
