$5.00 for 2x Panasonic 18650s 3400 mAh (plus like $7 is shipping)!!! If someone could check if they are legit that would be nice but I am pretty sure that they are.
You could also buy the Samsung 35E (3500mAh) which has better battery life than the 18650B for $1.85/$2.55 more too. http://www.ebay.com/itm/112173495496
Very good alternative to the 18650Bs and sold by genuinecells.
