Best Buy is currently clearancing out some of their home theater receivers for 10% off. But you can also get a 20% off coupon for open box items on their website.

The coupon is only good through this Saturday, May 7th.

Making the final price 28% off the original new price. My store is advertising 15% off open-box items, so I can use it for 32% off.

In any case, people have found open-box Pioneer 1014TXs & getting them for around $240+tax (reg. $349). They also have high end Yamahas (5790) & other receivers as well. Someone reported getting the Pio 1014TX for 50% off in Maryland, but YMMV.
