I paid that much for my sony ones about 8 months ago... But it's not a bad deal. My friend just got a 10 pack for $20, usually online prices are lower though.
I haven't bought something in a store in a while. I usually buy my big purchases online. Best Buy does have some occasional good deals, so I will go there.
But that doesn't mean I don't go there... I go there a lot - same with Circuit City...
