    I initially had problems ordering online (my stupid fault though) and the man there was more than happy to help me order the balls. They arrived in good time for free and I am very happy with my purchase. The balls are very good quality. Thank you for your help. CB Chivers.

    Located items Sunday evening, ordered via the on-line process. Received order confirmation about nine am on Monday, received shipping confirmation about two hours later and delivery to rural Perthshire on Wednesday. That's delivery and communications about as good as you will ever get. I only use this company on an occasional basis but they always have had whatever if was looking for and their delivery and administration has always been excellent. I will continue to use them without a single doubt. David McN (20 miles north west of Perth).
