I just checked and IBTanked has them in stock. I am not sure what ocean you are in, but if it is the Pacific OCD (IBTanked's owner) is located in California and the ship time shouldn't be too long.
Get yourself verified, they often have coops for them where you can
buy in bulk. You just have to be aware that coops take time to generate the interest, get the payments, order from China, then ship to the USA and then reship to you. But for the cost savings, and having a ton of them on hand, nothing could be better. I think I must have 20 boxes sitting in my secret stash hole under the stairs (shhhh, don't tell, it's secret!)
Now is the best time to get into DIY also. Everyone is scampering to get their high level NIC for when the FDA makes a decision on what to do about the wild west of ecigs these days. No one knows, but at the least I would think they want to tax the nic for the revenue and I for one don't want to pay a ton of taxes!
