You catch them, and breed them. Its illegal to ship hoppers across states in the US. I feel like I am having Deja Vu again. For the third? time any feeder you "Cant find outside of "British"" is illegal in the US to move across state lines, 99.9% of Insects are illegal to ship in the US, EU is not as harsh. You have to look at hobbyist sites that play a little loose and get lucky, or catch them yourself or get into your local reptile circles, with folks who can sell to you.
You have to be careful with buying from "Hobbyist" sites too. If someone has a PPQ 526 for an insect they can sell them, and you buy it without a permit you have broken the law. They do not have to ask you if you have a permit, as long as they do, they are not breaking the law, but you are. Its very convoluted and complicated.
They got taken off restrictions? I didn't know that.
