True North Vapor
This is NOT free. Even the 'free trial' which isn't clearly described is not free. The support team wont give a straight answer to the actual fee. Took me all of 2 hours to realise this is basically a scam. Whatever happened to truth in advertizing?
The Better World Company
This app is NOT free as advertised. I spent several hours over the course of almost a week installing and configuring the app, following their online directions for creating an account, trying to get my shop connected properly, bouncing around with customer service, and playing phone tag with their agents; all while thinking I could integrate with the Mobile-Free version already downloaded onto my phone. What they do not tell you up front is that in order to use the Shopify version you are REQUIRED to sign up for a paid web subscription to get an API key. They wanted to charge me $248/month to upgrade. I'll be removing the app and finding something with truthful advertising and more reasonable pricing.
