Recently purchased caulking from these folks and unfortunately I ordered the wrong color. However, they would only take one box back b/c the other box was open and one of the tubes was used. Problem is they charged me full for shipping and had me pay for shipping to send it back as well. The fair thing to do would have been to credit me at least for half of the shipping since they are going to resell the box I sent back as they mentioned! I will never buy from these folks ever again! Buyer beware!
