homelite 316689001 OEM SPROCKET COVER ASSEMBLY

The order was very professional and as good as I would expect from a store of your size. I was only miffed that early in the process there is mention of the option to be contacted in regards to an estimated shipping cost yet I did not see this option anywhere throughout the process. Where did I miss it and is it possible for your web designers to make his option more user friendly?
Thank you for your consideation,
Todd Merenick
