In store they were great and knowledgable. had an order to be delivered, building materials and an entire skid of concrete mix. The delivery driver delivered it all while it was raining. the concrete wasn't covered. He off loaded it and left it in the rain....uncovered. When I complained to the store NOTHING was done about it. It still sits in my driveway. It can't be used and I will not pay to dispose of it. I'm out about $800.
