Does Biden/Warren ticket, campaign merchandise signal the end for Hillary?

So I was looking through amazon yesterday, and came across these!! Does this mean Hillary is going down? Or, can anyone sell these things on there? Also, it has Biden and Warren?! Fairly weird?! For those who don't want to view the link, amazon is selling Biden/Warren pins, shirts, etc... for president and vice president!
