3.1 Setup on a budget. How did i do?

First of all thank you all so much for all your info! This site combined with a few other resources helped me out a great deal while deal hunting.

I hate to be one of those "is what i bought good?" guys but... could anyone perhaps answer this exact question? I would just like to know if i screwed up anywhere so i can bring anything back during the return period.

-I got a Harman Kardon AVR-1700 open box at best buy for $150
-While at best buy and perusing their open box items i also found a pair of Polk T15's for 35 bucks.
-Based on these polks and suggesting to match cone size etc i grabbed the polk CS10 center channel at full price from amazon
-For a sub and based on a few suggestion i grabbed a BIC America F12 with the idea i won't have to upgrade for a while

Basically I'd like to know if i made any mistakes or if i could have gotten a better bang for my buck anywhere. Also sorry if this is not where i should be posting this.

Yes i was very excited about the Receiver. To anyone looking for a similar deal use the best buy store locator and pick your store. From here you can view open box and clearance items. Also keep in mind the longer an item sits as open box the cheaper it goes and the more likely it will be that they'll knock down the price further. I have 2 best buys equal distance apart. One had this unit for $480 and one had it for $180. I asked a manager if he could do better than 180 and he marked it down a bit then they had a 10% coupon on all open box items that also applied.

I have but just mainly to text that that everything worked. The problem is i tested them with an MP3 off a jump drive and probably didn't use the best music. Combine this with the fact that i didn't have anything of any quality to test from as a base i am kinda blindly deciding if i like what i hear. That being said it did sounds pretty darn good and the sub/center channel has yet to arrive. I have my basement completely torn apart as i am building an entertainment center in to the wall so i am limited in what i can test. Just picked up a Panasonic 50 inch UT50 as well and i think i will be very pleased with my setup considering i stayed under my $1500 budget.

Actually that's the exact reason i currently have the basement torn apart. I'm fairly new to DIY home repair/remodeling so i figure this will be good practice.
