I've bought these before on ebay, but they take a few weeks to arrive:

Anybody know a better source or have any available for less than 5 USD each?  I would prefer to pay with btc.

Edit-
I found these, but I would still like to pay with btc so I will leave this post up.

Are they sold in-stores? If so which ones?
