Where to purchase oxalic acid?

[Davzbeez]

I have unsuccessfully looked at Lowe's for oxalic acid in powder form.  Does anyone know of a product label or product name that I could look for?  If you don't want to name it here, please pm me.  Thanx

I bought one at True Value and one at Ace Hardware.  It's in the paint department. It's wood bleach. You're looking for a small plastic tub that holds 12 ounces of oxalic acid.  I don't remember which came from where but here's what's on the lables:

Bondex Easy to use Wood Bleach (Oxalic Acid Crystals)
Savogran Oxalic Acid Wood Bleach

It seems like they were about six or seven bucks.
