Free shipping on a center channel speaker:
I recently bought this speaker and pretty happy with the performance. Its small enough to fit in most entertainment stands, but like most speakers is directional and requires you to be sitting in the sweet spot directly in front of it at proper height.
The matching bookshelf speakers also have free shipping so you can assemble a home theater system on the cheap.
Warning these max out at 60W so only for small rooms or apartments, not for filling a large room.
I've got Klipsch, SVS, Polk, Infinity, Energy speakers in my house and some DIY ones but none were this cheap!
Can put the money you save into a decent subwoofer, you'll need it. Sadly the 12 inch monoprice sub doesn't have free shipping.
