NFA Storage and transfer fees

[Mercula]

Getting my first suppressor soon. Trust is setup with SS, and now Im seeing mention of transfer and storage fees.

I get that if I buy them from SS online and ship to one of their powered by dealers there should be no transfer fee, but then that dealer can charge me storage of the item during the wait. Seems like this is the norm from what I could find. So if I buy from another dealer, and have it shipped to my dealer, I will pay tax, shipping, transfer fee and storage fee?

I am aware they need to make money on the deal too for the trouble and work. How has your experience with local dealers? How much did they charge? Do some dealers charge more because they really dont want to be bothered with it?
Thanks for your time.
