Rust Forge gives you the ability to get packs of their terrain at one discounted price over in their webshop.
From the announcement:
No we aren’t having another sale! This is even better. After many hours of discussion with our accountant, we decided to execu…fire our accountant. The reason for this is because we wanted to do a full time multi pack and he wasn’t cooperating.
So, we now have our awesome hard plastic shipping containers available at the normal singles rate as well as a 3-pack discount deal. You will save a few bucks buying them in the multipacks. Now there is no reason to not buy 3 or more! Why would you buy less, anyway. Seriously, you buy just one container and all the other terrain picks on it because its unassuming. You buy a 3-pack, though, and they become the talk of the tabletop with all the other terrain being jealous and a little afraid of them.
So use the conviently provided link below and go get yourselves some shipping containers for your tabletop gaming pleasures. I gotta go find a shovel!
