I found Home Depot great to deal with,I took a rough sketch and measurements to them and they gave me a computer generated plan with all of the material I would need, I could vary the types of wood and the prices were given for each type. They offered a 0 percent finance plan. Their price was the best quoted and I really shopped around. They delivered all of the material and brought it all around to the rear of my house. A few pieces of lumber were defective but I had no problem with replacement. A few times I had to go back for some building advice which they gave me in laymans terms. After the project was completed I had no problem returning any material I did not use.
