I never had an issue either, and use them exclusively. I admit, I'm a WL guy. I get most everything from them, my nic, PG/VG, and most of my flavorings.
With the recent surge in diy'ers, and the threat of regulations, nic orders have skyrocketed. Any company that gets bombarded with demand will go out of stock of anything. There is nic out there for purchase but it seems people want WL's product. There may be a reason for that.
I would rather see an OOS than get nic that has been laying around for 8 months before I buy it. I can wait for a fresh, top of the line product. They are real good at getting stuff back in stock asap. You have to take demand into consideration when you place your orders, and you can't blame WL for the increase in the number of orders, or the people that just ordered 2 gallons of it for their freezer.
Case in point -
Participation in the shooting sports/personal defense increased dramatically.
Its up to you to figure out why, but here's a hint ...
Threats of persecution. Threats of regulation. Threats of retaliation/taxation.
People got scared. People started buying/hoarding equipment and supplies.
Supplies and EQ went to ZERO.
Its not vape-zero ... yet ... but does it sound eerily familiar?
