Yes if it was close to the end of the year, and you bought refills for the next year, they would give you refills for the previous year (if they had any left).
A few months ago, we had a nice thread about refills. I ended up buying Charmmy Kitty refills (week on a page, also month on 2 pages) as well as the pocket size filofax week on 2 pages (but with pink paper!) both from ebay, both under $10, and mixing them up to get parts that I want from each. I also got the LV paper (lined note paper) and post-it notes from elux. For the rest of 2006, I ended up just making my own calender refills, as I have a hole puncher for this size paper and I am a graphic designer.
Since I have been using it, about 3 months, I have been much better organized. I love it! The rings are small though and I cant fit as much as I would like. I got the filofax credit card holder to put my library card, shopping discount cards, etc.
