I just went on the site and you are right, the prices have really shot up. My pool was around $11.5K, but now:
16' x 43' x 6' $15,750 (this is cut and pasted off their site)
We did buy 1 week before they increased the shells by $1,000 across the board. Maybe the cost of the resin increases with the cost of oil?
At the time, an 18' x 36' vinyl pool was $14,700 installed. I thought the FG was a much better way to go.
