Alter Eco is one of several "fair trade" chocolate brands. They put a lot of effort into reforestation and sustainable packaging. You can find some of their products in stores, but if you want access to their entire selection, or bulk quantities, ordering online is the way to go. Their milk chocolate bars are especially rare in brick-and-mortar distribution.

Sadly, they no longer carry their old Nut Butter Bombs, but their truffles make a great alternative to other round-wrapped-chocolates brands, with compostable wrappers. Their Truffle Thins are good too, with a "like an Andes bar, but classier" vibe.
