Query: two thumbs down

I knew I had made a bad purchase when the shipping charge was higher than advertized.I have used the system - lightly - for about three weeks and already one of the speekers has gone out. I should have shopped around. Wal-Mart has a similar system at a significantly lower price (particularly after paying $35+ for shipping).I wish I had shopped around more before buying this dog! :(
