I noticed years ago the phone numbers for Brecks, Spring Hill, and Michigan Bulbs were from the same area code and prefix even though there were two states involved. They were also almost consecutive from the same group which means they all had to come from the same office telephone switch. The three catalogs had the same account number on them. They are more like a brokerage than a nursery. Service was always great and they honored their warranties. Phone number arrangements always catch my eye as a result of my former employment.
