I've asked for assisance before installing the app and Philip replied very quickly.
The app is easy to set up, I used it to add an extra shipping area cutomized by zip code.
Excellent...and last but not least, free!


I used the app to add an extra shipping option for my customers in order to make a workaround for COD charges. PERFECT APP. Easy to use and finally resolved an issue i have been struggling to solve since i first launched my shop. THANK YOU FOR THIS APP WHICH IS FREE AS WELL !!!!!!!
