Best deal on a 5.1 surround sound at either Best Buy or Amazon?

Hi,

I'm looking for a surround sound system for my father. I know it's last minute as father's day is tomorrow but I won't be able to see him until late next week due to travel reasons.

Regardless I have hundreds of dollars in Best Buy credit which I can easily covert to Amazon credit via Kindle Gift Card purchases at BestBuy.

This is what I'm looking for:

Price range: Sub ~ $350
Specs: 5.1 system with HDMI input/output

After that I don't really care. He's a clutter freak with me so wireless rear spearks would be AWESOME but I've heard bad things about those and interferance issues but that was awhile ago and it may have been corrected.

I don't care if it is just receive and speakers or receiver (with built in blu) and speakers. He already has a cheap blu-ray player and although it may be worth upgrading I don't need to receiver to have any built in iPod or blu ray features

Also it is important to note that it isn't a huge room that this is going in. His living room is maybe 15' x 20' and that would be a generous estimation...

any help would be greatly appreciate.. otherwise I'm at the beck and call of a combo of sale prices and geek squad "expertise"

thanks
