BUYER BEWARE! I recently ordered flooring, grout, adhesive and strips at much lower price than local flooring company. I thought it was a great deal--WRONG! I based my order on their suggested calculations. However, I had so much leftover UNOPENED grout, adhesive and flooring that is basically being tossed. Unfortunately, you cannot return cartons unless 4 cartons or more? Really, your measurements must be really off to have 4 cartons of leftover materials. The flooring transition piece was basically a drawing and I couldn't tell that it was rubbish based on the drawing.Do not order Armstrong LVT transition piece--it is unusable. That went into the trash also. Given the cost of the overage, it would have been much cheaper to go locally with less stress. DO YOURSELF A FAVOR, unless you are certain of your needs, do not order from Efloors.
