As a loyal Edmund Scientific customer, I would like to request that US Mail be added as one of the shipping options on your website, especially to Canada which is not well served by UPS. In my latest on-line order, I had to pay an astronomical Customs Clearance charges directly to UPS in addition to the Shipping & Handling charges to Edmund Scientific, i.e., $65.65 CAD for UPS instead of $5.00 CAD for Canada Post!
In the past, I was able to specifically request that my package be shipped by USPS when I ordered stuff on the telephone, so I know it is certainly possible. I just want you to add this option to the shopping cart checkout section of your website for on-line ordering as well.
