Hi all,
Where does one find 5-gallon carboys of 12% bleach? Do you order this online, get it from a pool store (argh!), or from a warehouse/discount store like Costco?
Is there a significant cost-savings to buying it this way?

Also, where/how do you store it? The only place I could put it is in the garage along with other chems, etc.

Thanks!
Erica
