We are increasingly buying our groceries at a local fruits & veggies market for a couple of reasons: The produce are fresher, are bigger, look and taste better for some reason and don't come wrapped in any kind of plastic packaging with a very few exceptions. Oh and also it's cheaper.
We've also started to get more and more dried goods, liquids and detergents from local bulk shops. For a little box of deluxe mixed salted nuts at the grocery store, I'd pay nearly 20$. In bulk it's a fraction of the price. Plus, I use reusable containers so it reduces waste.
