I bet you could go to the Texas/Mexico border and buy a very good vaccine card forgery from the cartel. I wonder what their pricing is.
Whatever they were getting in the past for a vaccine card it should cost a little more now. The reason being, before it was based on convenience, and having less of a hassle.
Now besides convenience, there is the additional factor of unvaccinated people being charged more for tests etc.,so the card has more value. -Tom
