I was buying a printer and saw this on the Canon website. Nice bonus if you're in need of a printer.
"Purchase an eligible Canon PIXMA printer from a participating retailer between 1 October and 31 December 2011 and register your purchase via this website to receive a BONUS Retailer Gift Card, valued at up to $50.
Shame this only got posted now, just bought one yesterday from msy, and only because couldn't pricematch at OW because the didn't have stock.
Also the eligible retailers are, Harvey Norman, Officeworks, The Good Guys, JB Hi-Fi, Bing Lee or Dick Smith Electronics.
