Please be warned, a delightfully odd shop but not a place to do business or trust among other issues. Their return policy is misleading, useless and seems deliberately dishonest. I agree with T.T., do

This is the place to get lightbulbs from an expert who helps customers understand LED vs incandescent and how to assess what type of light works for each person. Simply the best in Portland.

Ridiculous return policy. Easier and cheaper to find what I need online. Don't waste your time.
