When I first saw the price, 2 Gal canister for $24.00, I said no way am I paying $3 per quart for Powerade.  Then after clicking the link I see it's eight 2 Gallon canisters, not one.  That's more like it.

FWIW, though, there was the following little caveat:

The purchase and use of POWERADE Powder and all other POWERADE materials from this site for residential or home use is prohibited.

I don't know how aggressively they enforce this...possibly not at all...but I figured I'd share it FWIW.
