I prefer to buy things in bulk as opposed to buying products individually. I’ve always been a big fan of places like Costco where I can buy massive amounts of the products I need for decent wholesale prices. I do this with food – preferably with the kind of food that doesn’t expire too quickly – and I do this with many other different kinds of products that I use regularly.
For instance, I do this with products that I use to maintain my car and my boat, mostly because I believe it’s better to already be prepared for a problem or an oil change or something like that than it is to not be prepared at all. If you’ve got enough bottles of two cycle oil, you don’t have to go out too often and find more of it, as long as you keep the oil in a safe place.
