I'll see if my hobby store stocks it on thursday. I need to go for an eye appointment then, and I'll have an hour to kill anyway, so I can see if they have the primer, and pick up a mini or two while I'm at it...
But as far as I know, they only carry GW. Of course, that's just at the very front of the store in the minis section. I'd imagine, since they carry plenty other hobby materials, they'd have more then just GW stuff...
