I have read in many places that the USPS bases its quotes on weight and disregards dimensions. I don't think that is true any longer and I think changes were made to uc_usps that essentially
'broke" USPS quotes.
All of my products have dimensions and weight. When I submit the "calculate postage" button I invariably get:
Dimensions are missing for package; unable to calculate postage. Additional Info: All dimensions must be greater than 0.
I suspect since previously USPS didn't require the size of a product, perhaps dimensions are overridden and set to zero? And maybe now USPS is taking in that information and rejecting it?
EDIT: I was about to submit this issue, when I tried one other thing. I was able to add one product and get a quote without that notice. It only happens on orders with more than one product. You can try it our yourself at:
http://horizonsalesenterprises.com/catalog/bongos just be sure to add two products. (By the way my configuration is set to "Each product in its own package")
On a side note: I just noticed tat regardless of whether you choose "Each product in its own package" OR
"All products in one package," you cannot choose the options for insurance or to require a signature. Why?
