“Ordered the wrong part for a faucet, texted them about and pictures of what I needed, they let me do a refund and they didn’t have the exact part but sent me a link to Kohler who did have it. They’re so helpful, I’ll totally order from them again. I’ll probably text first next time so I get the right thing in the first place :) ”
