Dollar Tree (plastic organizers) and Target (dinos) scores!
The plastic organizers have a great texture on the inside (2nd pic) and can be used in dioramas as troughs for animals, long storage bins or other things.
The pink dinos have an awesomely shaped head (3rd pic) and may or may not get their heads transplanted onto better, articulated bodies. But even if I just repaint them (the bodies aren't bad at all, just need some putty where the heads attach as there are visible seams/gaps), they are still great for $1 each.
