It's just the fact that buying in bulk for the average bloke is way cheaper in the long run. A smarter way to go about it.

To have in stock and carry the 1 litre size is good. An issue was that it was located on the bottom shelf and difficult to find being a smaller container surrounded by larger containers it really should be at better height and viewing line.

Great quality and perfect for my car. The change kit fits the bottle inside as well so it's all together in the car when I need it
