I think Rx Drugs are cheaper in Canada.
Maybe Canada could start there with online sales to the US.
You already can buy prescriptions through Canadian pharmacies.
I’ve gotten a couple for far cheaper than I could in the US with my insurance and the co-pay.
That’s not always the case, but I just check for competitive pricing and go with the cheapest.
You have to carefully investigate to make sue the pharmacy is legit, as there are scam operations that work out of Canada (allegedly). There’s a certification that legit pharmacies can have.
