With the cost - I was surprised to see that we were paying so much compared to everyone else in here for DH's vasectomy and I mentioned it to him. He said the place he is having it done had a price hike on the 1st of January from $380 up to $500. I don't know if it would be similar everywhere, but it might be something to keep in mind.

DH doesn't have to give a sperm sample until 12 weeks after. When they cut his tubes, they cut a small section out and will send those off to the pathology lab for testing. I am not sure what they are testing for, DH said something about making sure they removed the right thing

Can they take in the sperm sample from home? Like can they "supply" the sample at home or do they have to do it on the spot sort of thing?

And CRAP 20 times in 12 weeks LOL. Thats a lot of pressure on me! I think when DH is ready to do this he will have to do a bit of self pleasure LOL. I don't have that high a libido!
I think they do it at home and take it in but has to be within an hour after they produce the sample and there are a bunch of guidelines on that too - organising a time to drop of the sample beforehand, the sample has to be collected within 3 - 7 days of last ejaculation (and days since last ejaculation have to be recorded on the outside of the specimen jar), keep it in your pocket until you drop it off so that it is as close to room temp as possible.

Fun times ...
