I've been purchasing from Inland for over 15yrs. I've been extremely pleased with the product, as well as the professionalism and friendliness of the staff. Very prompt delivery from time of purchase (usually 36 to 48 hours). I would be remiss without saying what an asset Marshall is to your company, knowledgeable, professional & friendly.
