Ya, stock levels were jumping around a lot this past week or so, as they limited stock and refilled it from time to time. So if you checked out and it went through then it's good to go. I mean they weren't out or anything just limiting online stock to try and keep up with orders rather then letting 10000 orders come in and getting further behind, that way no one is waiting a month for their order.
On site stock level is only for volume control, not the amount of Nic they have on hand. They do orders as they are received, but of course some of the workers are new so they might take longer to get an order boxed up compared to those that have worked there longer. (Just my speculation) So I doubt what you're thinking is going on at all
They don't have a stock issue, well maybe some flavors out of stock, but Nic is there but they're just limiting purchases so they can keep up with orders. They just moved, and April is upon us, so 1000's of people are trying to buy Nic last minute, so that's why all this mess is going on right now.
Sorry you're still waiting, hope your order gets to you soon!
