This plugin was a total waste of time. After installation I couldn't add USPS to any shipping methods and could not get it to show in the cart during checkout. It appears the author hasn't been around for at least 2 years. I've asked for support and as of this review it has been five days with no reply. This is costing me lost revenue.

I know this says it has not been tested since 2016? but I just installed it on a new woocommerce shopping cart I am working on a website and it works just fine!!

Unlike another free USPS plugin, this actually returned accurate prices and does as advertised. One sorely lacking feature is the ability to return potential shipping rates in a specific order, like by price in ascending order. Others have requested the feature, but as of today it's still an issue.

This plugin is great. Provides accurate, real time pricing with actual weights for products by zipcode. Adds the product weight correctly and returns the correct cost. This is how it should be in any e-commerce shopping cart, including Woocommerce. I really like the feature of toggling on/off USPS commercial based pricing. Great Job!
