safety of "tin" cans dented in shipping
From the  USDA :

Is it safe to use food from dented cans?
If a can containing food has a small dent, but is otherwise in good shape, the food should be safe to eat. Discard deeply dented cans. A deep dent is one that you can lay your finger into. Deep dents often have sharp points. A sharp dent on either the top or side seam can damage the seam and allow bacteria to enter the can. Discard any can with a deep dent on any seam.

I definitely would be hesitant to use any cans dented like the one in the picture. And as per my comment above, I would contact Amazon.
