Joe, kindly need 2 quick replies. 1) is this a legitimate supplier (35% off, free shipping through Dec 5) https://weshipfloors.com/ (we’re taking your advice ordering Mannington Adura Max. 2) What’s your rule of thumb for ordering amounts (5%, 15%, 20%) i.e., excess waste. (Doing 2 bathrooms, hallway, 2 closets, 2 pantries, kitchen, living room). I’ll follow up later with the blueprint. I watched many of your videos. Thanks.
