First post, harsh. Newer companies often become blasted with orders at holidays. Been there, done that. As anyone who has ever been in the retail or internet business can attest, holidays mean lots of temporary help, incoming shipments not showing when expected, etc, etc. It can take years for growing business to stablize and allow then to get the near prefect system that is needed to handle holiday rushes. You almost never hear a bad post about PSA, so obliviously they are addressing growth problems well. Much luck to them.
OP I have learned in the firearms hobby that often you are dealing with small to mid size businesses that attempt to the best of there ability to full orders completely and quickly, but sometimes delays happen. I don't lose sleep or let my world come to an end because a part for my hobby was a few days later then I expected. Life is way to short. I have ordered 3 gunstocks from Boyds. Just the nature of their location to mine, means UPS has to go through 2 extra distribution centers before it get to me. Sometimes that means days in extra time. I like their products so I order again and again and wait.
