The sign for my retail store has weird sized light bulbs. I had to phone around to see if certain stores had this size. All the major department stores said no. When I contacted Nedco, not only did they know what I was talking about, but they had tons in stock! It was really easy to find and when we got there the staff was helpful and cheery. We walked out of there with more than enough light bulbs to illuminate our oustide sign! Wonderful place!!
