Well the CE is available at Outpost for 79.99 (instead of the 89.99 price everywhere else). But you'll want to add about 6 - 8 dollars onto that for shipping. So you still win and don't have to leave your house.
Otherwise... I'd say sometime during the month of May Best Buy will have a 10% off of one item weekend. So you could go that route if you don't mind waiting.
Hope that helps (on the CE).
