The Better Packaging Co

A lot of apps promise you the world but putting that into play can be a whole other task. I've been incredibly impressed with the support for this app, especially since it's free. CustomShip handles regional pricing really simply. It would be awesome if you could use you weight/price granularity as it hurst the brain a bit to work in cents and grams for our products but this does not effect functionality and I'd happily recommend it.


Great app! I was able to configure many different shipping rates to different regions/zones using filter logic.
