IMO you should consider keeping your business local. A reputable Hardwood Flooring Dealer, or better yet, a reputable Independant Licensed Contractor, that does his own installations
, ( this will also save you money in the long run ). Ask around and find people with a proven track record.
If your installing the floor yourself...You can still purchase the material through a Contractor. Usually Contractor's have more product knowledge than the typical salesman, and the "hands on" experience, and can point you in the right direction. Some actually purchase at the same cost as dealers, but dont have the overhead.
