Yes, at least you can at our local store. I'm not sure about what the options are for hoppers...as far as how many days they offer. You'd have to call them to find out, unless someone here knows. And they are the hard, plastic tickets.
If you're looking for something specific like a 3-day hopper, I'd call first. My local store only had 3-days for adults, and only 5-days for kids. It didn't matter to me since we were going to upgrade, but it could have been a real pain otherwise kwim.

I would suggest calling too since you aren't in Southern California.
But if it doesn't work out, on Disneyland.com the etickets, you just print out, take them strait to the turnstyles when you go to the park. They scan them and give you the ticket you paid for. Very easy to do.
