Off topic. While it makes sense to explore oil in the US and start drilling where they already know their is oil is fine and dandy. But!! By the time they get around to it, were looking prolly around 6 to 10 years if not more for oil to be pumping out of the ground. A lot can change in that amount of time.
On topic. I think a lot of manufacturers are building off of last years supplies, from what I have heard, Jacuzzi and Sundance have purchased all their sheets of acrylic a few months ago for next year. I don't know if they have taken delivery yet or if its a price lock guarantee on said product delivered. I am guessing some of the other larger manufacturers have done the same.
Hotsping, Arctic,Marquis?
