More Bulk Barn type stores. Offer more products. Include a large recycling/storage feature within these stores.
The stores could sell their own storage containers, that are recyclable. People then fill their purchased containers, instead of getting new containers every purchase. This is good for Bulk Barn type foods, liquid detergents, condiments, milk/cream, and etc. This service model would need to have different store outlets, to offer the different goods. You should not be moving food, with detergents in the same building; if you do it would need extensive health and safety measures built in.
