We are now using the Viart cart and so far its great and the support is excellent.
 
But I have discovered a shipping problem that needs to be addressed. We ship packages in all sizes both in the US and International. I have setup up USPS and Fedex and in the Fedex module used parameters of 10" x 10" x 10". This is fine for most packages but I also have items that are 45"x 18" x 10". In this example Fedex would return a rate of approx $10 where it would be $40-50 + based on the size.. This is for ground rates in the US. Not easy to absorb that much money lost.
Then shipping Internationally, it gets even worse.. Most of the shipments I send by USPS, many of the countries have size restrictions and specific shipment methods allowed.
 
I have used a cart previously where I could input these sizes for each item that required it with the weight. When the order was placed, these requirements would be sent to the USPS and Fedex rate servers and the correct shipping charges would be used.
 
Has anybody come up with a solution yet?
