In my area, there are a number of mom and pop, old-fashioned hardware stores that have been franchised by Ace hardware. Most of these places maintain a "self-sufficiency" section from the old days and sell a lot of canning/jarring equipment. This section always surprises me with how much homebrewing/winemaking equipment it has, including 5 gallon carboys for 29 bucks. I do live in wine country, but it would be worth a shot seeking out one of these old country hardware stores in your area.
edit: I bet they could order you quite a bit of stuff as well.
