I am looking for something that won't cost too much.
It's not like I live in the garage.

In the late fall, I bring all my glues, paints, aerosols and caulkings in from the garage and store them in the basement. The fuels, oils, greases and solvents are not damaged by freezing and stay in the garage all year round.
You will not find a cost effective method of keeping an entire garage above freezing all year round. The cheapest operating cost method would be to install a small natural gas furnace in your garage. However, your initial capital cost would be prohibitive.
Have you considered building a small heated cabinet for storage of your perishables? Of course you will need to vent it externally to prevent buildup of combustable vapors.
