A bit off topic, sorta. Mods, please move/delete if needed.
When you purchase a can through your SOT of choice, a shop that sells/distributes cans, or from wherever, do yourself a favor & verify that the can actually "physically" exists (not just existing on paper) & is in inventory. A local SOT had a situation with a shop that is known for selling silencers where several cans were paid for, without the shop actually being in possession of them. They were not being shown as "Out of Stock" nor was the SOT made aware of the cans not being (physically) in stock until later, when he made a direct inquiry. Had he known, he could have sourced the cans from companies that actually had them, instead of someone that was representing themselves as physically possessing them.
Waiting for approval is one thing, but having an avoidable delay added to the process shouldn't be something that one should have to endure, IMHO.
