Packaging is simple but that's how they keep prices down IMO

Don't be fooled by the simple packaging folks. All those bright pictures and fancy logo printed plastic bags other stuff comes in costs money. BAS is keeping it simple with their packaging and that helps keep costs down for all of us. Once you open the bag and smell, touch, and see the quality of the castings, nothing else will matter. This is my first purchase of worm castsings from BAS but I assure you it will be the first of many. I will no longer purchase from Amazon or other sources - you want the highest quality for the best price? Then you should order from Build-A-Soil, period.
