Lou ,
No apologize necessary .
There is 2 reasons why I have not installed an automatic-shipping-cost-calculator
First it’s time-consuming to get it setup right at once , since I also do international shipping ,
and I only want to charge actual shipping costs instead overpriced shipping-charges as it happens in some online-stores ,
plus a lot of guys want some other stuff I don’t have listed ,
and I like to have that little personal contact with my customers ,
even if it’s just an email with a few lines about the shipping-charges …
bottom line it's a hobby and we all want to have fun with it !
