I'm hoping you can provide me insight into a plugin i purchased for woocommerce for USPS shipping rates. it's a general question...Where do you think the issue lies if the USPS plugin doesn't return the correct rates? A million times i've compared the weights of a website 'm working on with the rates that the USPS site returns...Standard post is correct but Priority Mail is the one that is wrong. Not sure what other infomraiton to provide you about this so let me know what would help. Can you offer any advice?
