Hi 15X and all,
Most if not all commercial web sites provide additional contact information including an e-mail address. When in doubt, ask. Recently I had a special order diplexer made to my specifications and found the sales manager's e-mail invaluable. She not only was extremely helpful all down the line but followed up with a telephone call (must have looked me up) to enquire as to my satisfaction with the product and service!
Hats off to Mrs. Sniva Lee of Tin Lee Ltd. Toronto Canada!
