Is this Normal from a known breeder?

I emailed Garrick, and he will be on tonight:

The missing puzzle piece! I knew from my experience with Garrick that not sending a replacement didn't sound right. I had to wait two weeks for the weather to warm up enough in WI to get him. As impatient as I was to wait, I'd always rather have a live snake and mine arrived alive and well.

Especially with expensive snakes I wouldn't do anything that would negate the live arrival guarantee. I think it's way more than nice of Garrick to offer a deal on a replacement snake when he was shipped when it wasn't deemed the right time.
