Where to find 12% bleach

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

Here's a post by PoolDoc on the subject: http://www.poolforum.com/pf2/showthr...ighlight=holes

Kurt (and PoolDoc),
Thanks for the informative post. My initial motivation for wanting to know about the 5-gallon carboys had more to do with convenience (I hate running to the grocery store/Target, etc for bleach) than cost. However, I thought that increased savings would be great, but I see that there isn't much savings to be had. In addition, I was a little worried about storage of such a large amount of (maybe) stronger bleach and it appears I had every right to be!

While reading PoolDoc's post I finally realized that I should take advantage of my grocery delivery service and use it for ordering my bleach. :rolleyes: Why didn't I think of that sooner??
