There was a law passed some time back in the US that prohibits shipping of vaping juices and nicotine base to consumers. All the retailers were given some time to sell off their existing mail order inventory and I think the absolute deadline was the first of April.
My normal juice seller has been reducing inventory for some time and my backup seller will no longer ship after today. My primary seller quit shipping a week ago and the secondary seller will no longer ship after today. The secondary seller is getting out of the juice business completely.
So don't expect to buy juices from any on-line stores in the US. You might be able to get them from Canada or overseas, but they would have to get past US customs.
