All of the Farmer's Delight food crates (Carrot Crate, Potatoes Crate, Cabbage Crate, Onion Crate, Beetroot Crate, etc) can be sold through the trade station for 1 silver each, however the Thermal Series Crate of Apples cannot be sold despite having the same 9 apples per crate recipe.

1.2 added an apple crate trade, closing this now.
