USPS has increased their shipping for domestic priority on dimensional (DIM) for things over a certain size . Until now, I pretty much put in the weight and "until now" have been getting accurate shipping price. But now that USPS has changed their rates for certain size packages the module is charging mush less that what price I get through "stamps dot com" when I ship the product. Like I just got a an order for a package that was 1lb-5.4 which was 31x5x1 and my cart charged $13.16 but when I put those numbers in "stamps dot com" it cost me $18.56 to ship it. Just increasing the weight of each item will cause WAY to much to be charged via the cart for the item if I'm sending to Canada. I'm thinking the fix for this is a dimensional thing in the product description. Maybe there is a plug in or a fix for this already. I have looked for this here in the forums but I have not seen it.

Does anyone know the fix for this???????
I understand the problem.

I have been running in to this kind of issue for A LONG time... UPS went totally dimensional a while ago, so our weights are all bumped up to cover that. Using the UPS Worldship program you can see what the "shipping" weight is vs. the actual weight in the detail when you input the package dimensions.

Because of this, when USPS over quotes/charges international we refund the customer the difference. Yes, it is an extra step when shipping, but doing it this way prevents us from having to pay the extra shipping.
