Architecture is ALL Wrong

I downloaded and played with this plugin and if you have a site with more than 50 products, this plugin is architected all wrong. All the settings are at the product level! This is wholly unworkable and unscalable for any real e-commerce site with 100’s or 1000’s of products.

There are no rules at the site or product category level.

There are no ways to integrate your credentials for various carriers (e.g. UPS, Fedex)

There are almost no real features.

Terrible and very expensive at $20/month. Their corporate site is unusable to boot. You log in, but there are no features to use! You can’t edit your credit card, cancel your account, change user name, etc. Completely unusable website and plugin.

Good Product, Great Support.

Product works well, and support responds quickly.
At first I did not like the pricing structure $19.95/mo for 1000 calls, and then $29.95/mo for 10,000 calls. but after analyzing a bit more, other plugins were going to cost me $69 per site and I needed UPS & USPS on 4 sites, so this will be cheaper in the long run. If you use USPS Flat Rate Boxes, be prepared to add-on the 4.95/mo to give you the flexibility you need. We strictly use Flat Rate SM, MED, LG boxes only, and the default plugin without the add-on compares the flat rate against the priority rates, which does give the most accurate rate, but for us are only offering the flat rate boxes.

Better than separate plugins

I had separate plugins for shipping with USPS, UPS and FedEx. They worked fine, but I wanted to add DHL and it seemed silly to have so many plugins running. Tried this one and found it very easy to set up. When I did have a question, tech support (I always seemed to get Doug) was terrific. Most of the time he actually answered the phone and when I had to leave a message I got a call back within 15 minutes.
Lots of documentation on how to set up everything.
Highly recommend.

Amazing, a must have plugin!

This is a must have if you ship or dropship through USPS, UPS or Fedex. Not only does the plugin work as advertised, the support is out of this world. Always someone right there to help and they know their stuff. Any issues are fixed in minutes. Rates given are perfect once it is set up correctly. Get this plugin now!

Trail ware? Really WordPress?

As a long time user / contributor I find it offensive that crappy trial-ware lole this plugin is allowed in the WordPress Repository. GTFO. Go peddle your crap to DotNetNuke or PHPNuke users. Oh wait everyone stopped using them because they suck and let things like this in their repository.

Perhaps it’s time to jump ship on WordPress as well?
