Help, No crickets for winter months.

My Leo's are on a steady diet of crickets at the moment, but come mid-fall all stores within a reasonable distance of my house stop selling feeders of any kind. I've had a Skink and Beardie for years without any problems, but they are not limited to live food like Geckos are.
My question is what do I do once the supply stops? I've tried many times to keep feeders alive but it never seems to work out, and since this is my first year with Leo's I am reluctant to shut them down for winter, seeing as it's not just 3 months we're talking about here but at least 5. It just seems unrealistic to expect them to last that long without any food. Help?

Where in GA do you live? Most ++++++++/+++++s carry year around. If none are close, consider looking for a south eastern cricket breeder. There are many who will sell you 500 at a time, which could last up to a month if you spread it out right.
