I've removed the links, as we do not allow discussion of sources here. I will say that there are clearnet sites that will send you psychedelics, but there are also scams. The ones you listed seem pretty sketchy to me. I'd be wary of sites that sound so blatant. And the similar layout seems quite fishy, too. Since source discussion is not allowed, I am also closing this thread.
My guess is they're scams trying t9 get your money and won't send you anything, and they created several sites to try to find more people in more internet searches.
