Received an email from apple this morning of an upcoming apple sale event this Friday. As usual apple have left no other details but from what I gather this Is the only day of the year apple have a sale.
Not sure what will be discount but anyone planning a big purchase might want to hold off till Friday just incase.
Hope this helps someone!
Edit - available online and instore, looks as though macs, iPad, iPhone, and iPod will all have a discount.
