Amazon has price matched "Don’t Starve" on Steam. However, Amazon’s version is a Steam key with both "Don’t Starve" and "Don’t Starve Together." It has a 5×4 format (e.g. AB1C-2D3E-F45G-6HI7-8G9H). There’s no gift link option. The Mac key also works for Windows.

The key activates for both games. It activates if you have only one game, but you won’t receive an extra gift copy of the game that you already own. It won’t activate if you have both games. Unlike the Steam bundle, you won’t receive an extra gift copy of Don’t Starve Together.
