Fry's has the pair of pioneer bookself speakers for $68 with free shipping. YMMV for shipping though, I was wanting to pick up the center speaker for $50, but when I checked it wasn't shipping as advertised, it was just available in store.
Shipping was a little screwy, first it advertised free shipping for any options, then it removed the item for my cart, then it charged a minimum of $15 dollars for shipping. But that charge was removed in the final order form. So just pick the cheapest shipping option and then shipping should come up free in the final bill.
