Marketplace
I saw this on MX ad yesterday which states that the sale will start Friday, but it seem that it is already active on their website.
Apparently, this has been a regular promo for Dick Smith lately. Myer only had $100 off during their Secret sale yesterday http://www.ozbargain.com.au/node/58340.
Hear a radio ad for this today .. didn't state a time frame jsut 10% off Apple at DSE. So seams to be on right now.
Though this almost seems to be the norm at DSE
