In the past three years I have bought a lot of paint. In general I like Depot’s better than Lowe’s. I can’t really tell a difference in the latex I bought from Sherwin Williams and it costs quite a bit more. However, Sherwin Williams does have some things that the others don’t – knowledgeable staff, enamel paint, etc. I also realized what a markup they have. I was buying some specialty paint and noticed they carried Zinser BIN, which I have been using on my trim. They are charging $45 a gallon. I pay $23 at Lowe’s for the exact same prepackaged gallon.
