I've been looking at a particular soundbar for a while now and thought I should buy it for myself for Christmas. The Sony HTST7 was arounnd 1,300 and was on sale for around 1000 at most places. Then I found that CompSource had it for around 690 dollars. I couldn't believe the price. I hesitated for a day or so and the price went up to about 703. I was very worried about the purchase how they can have the price so low. About 300 lower than anywhere else. I took a chance and purchased it and since I was able to pay with Amazon pay, I felt a little better about it. It turned out to be a very good purchase. The unit arrived quickly, within days and the box was in good condition. CompSource kept me in the loop about my purchase and shipping and tracking so I felt better about making the right decision to purchase from them. When it arrived, I can tell it was new and unopened and very well padded. I couldn't believe that a soundbar came in that huge box. It's quite a heavy unit too. The quality of the soundbar is unbelievable, sounds great also and looks great. I'm very happy with the purchase from CompSource and will certainly look here first whenever I need to buy something in the future. NxP3
