That is great to hear! What we offer as a company is a pre-paid program in the summer which locks in tile prices in the fall at a reduced rate AND guaranteed delivery within 24 hours. As far as the price increases go, it is unavoidable. Resin prices continuously increase as our country continues to ship raw materials overseas (mainly China). I know a lot of farmers, contractors, etc get antsy about the prices, but it is still, and will likely always be, one of the most sound investments you can make to improve your ground.
What are you running for mains and laterals?
I have seen the driest of grounds and the wettest improve by adding tile. Yield monitors don't lie.
