I had a problem at Henry's recently when I ordered and paid for a litre bottle of HC110 and got a 473ml bottle. The catalogue number had changed up, so they simply used up the old inventory without realizing that they were gypping their customers. It took over 2 MONTHS, many emails and several phone calls, (some of which were never returned), to finally get it through to them that they had screwed up.
While staying in Victoria, I went to a great shop called Lens and Shutter, I believe. Knowledgable staff and a pretty good inventory of analogue supplies and equipment. Have you tried them?
