Yeah, I didn't think it looked too expensive but thought it worth mentioning the alternative. As much as I hate going to Bunnies.
I'd have to check in the garage but I'm pretty sure it comes in 1kg tubs for next to nothing. It's usually listed as rust and stain cleaner in the cleaning section. The active ingredient will be listed on the front of the container, as is the concentration.

Mind you I'm only going off of what I've read for passivating stainless. Personally I only ever use the stuff for cleaning decks.

I had a look at bunnos for BKF and didn't find a thing, I got the powdered stuff in the little tin. Going to do a bulk order from the states soon if no one can point out oxalic in bulk for cheap, this stuff is tops!

The first one is the stuff I use all the time for cleaning decks and paving. Just be aware that these are concentrated acid and please take the time to read the MSDS links.
Even when diluted this stuff will burn your skin pretty quickly if you get it on you. It's not like in the movies but it will leave you some nasty burns if your not careful.
 
And for those that were wondering about the concentrations.....

100% w/w is pretty Fing strong. 2kg was around $10-15 from memory.
