Where can I get low priced FRS Healthy Energy?

I ran a 5K a few days ago, and before the race I sampled a can of FRS Healthy Energy, Peach Mango. It tasted good and I sprinted the whole race without even being tired. I'm positive that I could not have done that if I hadn't had the FRS. I tried to Google how much it would cost me, and it was a lot! Anybody know where I can get cheap cans of FRS? (I prefer peach mango). I am up to trying chews too if they work as well as the cans. Thanks so much!!
