S&W repair question

[comp124]

I just sent my Model 19 Combat Magnum back to S&W for work. Called them on the phone, they sent me a shipping label and instructions via email. Purchased a box and bubble wrap at Walmart, sealed it with a letter explaining the issue. Took it to the FedEx location near me in Johns Creek, Ga and dropped it off. Didn't even ask me what was in the box.
