Store bought almond milk is really pathetic. It's basically just water with just around 2% almond. If you really want almond milk, you'll need to make it yourself.
Just soak almonds in water overnight. Put them in a blender with some water. Blend it thoroughly. Then finally, strain that mixture through a nut milk bag.
That's all it takes to make almond milk.
The leftover nut powder doesn't need to go to waste since it can be used for other recipes.
