Who/where are Solo Direct?

Contemplates

Im pricing round for a fill of heating oil before the cold weather returns, and the Cheapest Oil website gives Solo Direct as being the cheapest by a fair margin. Just looking at their website though they don't give much away as for their location, or who they are. Has anyone on here used them and anyone got any reviews?
