I'm in Australia and I've seen HCl (%33 wt/wt) sold at most building 
suppliers, or any place that sell cement. Its usually in 5L or 20L drums 
for brick cleaning/etching.

You may need to venture out of your domestic area and go somewhere more 
industrial. I'm lucky that I live in on the side of the city which is 
fairly close to a number of large industrial areas.

You best bet is to look through your local business directory and start 
phoning around. That how I've always sourced chemicals, those a lot more 
exotic than garden variety HCl.
