We've bought paint from Sherwin Williams for years and recently returned to them for the paint for our bedroom. Their prices might be a little higher than Home Depot, but the service and attention to detail is completely worth it. When my husband and I were trying to decide on a color and not having very much luck the clerk was more than patient with us, even offering helpful opinions now and then on what colors he liked/didn't like. When we finally narrowed it down to a few choices, he suggested that we take the sample book home to see what we would think of the color in our own environment. He even told us that if we found a color on something that we could bring it in and he could color match it for us. The quality of paint is exceptional and you can't find such attentive service at a larger retail store.
