USPS Module trouble

[Joe]

I am using Shop Site Pro (8.3) with the USPS module for real time shipping quotes. When I use the online USPS calculator for Priority Mail it shows a charge of $4.60 yet when I use the module in my shopping cart for the same item it shows a cost of $6.25 -- any suggestions what may be causing this discrepancy?

Thanks

If you are using an add-on module for USPS you would need to contact whoever you purchased the module from (Lexiconn?) for assistance with it.
