Hippie Pants review for Postscript SMS Marketing

Shiny modern app but it does not sync well with Shopify and it is deceptive. They don't mention that "international" SMS is 10 times (yes TEN times) the cost of US SMS. It's not mentioned on their app listing nor on their pricing page, only hidden away in the documentation. By international it literally means any other country so if your store is strictly restircted to US you're better off with one of the other SMS apps.
