It really seems funny that gas can drop over 1/2 and some in price in 6 months (Or less). I refuse to believe that supply suddenly changed. Or that demand changed that substantially.
I clearly do not understand that industry. However, it really makes me feel better about solutions that you sell instead of consumables. I can change the solution, new products come out every day. If your selling unleaded, you may make some money this summer and not this winter.
Which brings us to selling. Sure there is selling in the gasoline market. But it is a really different market. If your company is driven by sales, it can produce a constant revenue stream versus a really inconsistant one. However a messing with sales or having a poor team will result in the same.
