Where can I get empty five gallon water cooler bottles?

I used to have one of those five gallon plastic water cooler bottles, the kind that sit upside down on the water cooler, as a coin bank. I was cleaning out my closet, moving the bottle around, and the plastic cracked open. I was wondering if anyone knows where you can buy one empty (sans ebay).

I have some empty 5 gallon water jugs from my water cooler at work. Can I use them as carboys to brew beer/wine?

Plastic ID is 7 and it says they should only be used for water.

I have an electric 5 gallon water cooler and I noticed a little bit of green slime inside the water reservoir. It it safe to just wipe it clean? Should I disinfect it? With what? Thanks
