In the interests of full disclosure, the code given also gives me an extra entry into a competition - but you can get your own code direct from the site with the link on ozbargain(after you answer some qu's).
This store has a huge selection of prints, posters etc as well as doing framing, depending on what you're in the market for 15% could be a pretty huge saving. I just had a fiddle with their site and they'll let you play around, try different frames & give immediate prices. I haven't bought from them but they look good - feel free to comment if you've had experience.
(BTW, when I went to http://www.picturestore.com.au/featureselection.aspx?id=257 it gave me a one day only 20% off code which was 22sept - might be worth checking there again if you want a better code)
