Rates do not match those from usps website
-
Hi there, we’re using the basic version of your USPS plugin on a client’s site and we have noticed that the rates calculated by this plugin do not match the rates given by the USPS website, despite identical measurements and weight. Oddly, not all of them are off — just occasional orders to various zip codes it seems.
Do you have any suggestions that would you explain these incorrect results? All should be using Priority mail large package. Can you please tell me if there is something I should be doing or configuring differently to improve the accuracy?

Hi Etellewyn,
The basic version of the plugin is well suited for small business owners as it packs every item individually
kindly make sure that the no of packages is going correctly.
If the problem persists provide me the debug request and response.
Hi Ni,
I don’t mean to bump this topic as it says resolved but I am getting the exact same issue. I just got an order today for a bottle that weighs 4oz (a 30ml bottle). The customer chose First Class Mail Parcel and it said shipping cost was $0.34. When we checked the USPS site, it said it would cost $2.60 to ship it out. It was a single package as you mentioned in your previous post. Could I have setup something wrong?
Also here is the USPS Request:

Ounces on the request is showing 3.20 oz but the product variation on my specific test order is only 0.20 oz. I also noticed that the dimensions are not showing up either on the request but I most definitely have dimensions setup on my product variations.
Hi,
We can see the rate ‘2.60’ is already there in the response. Please make sure that you have selected all the services from plugin settings.
This is also strange that dimensions didn’t get passed in API request. As it is a variable product, I would like to suggest you, to double check dimensions under each variation.
If you still face such issue please send us the screenshot of the product page (with shipping details), cart page and plugin settings page.
