Pirate Ship: CheapARR Shipping

IT JUST WORKS! Whenever I use other (paid) platforms for shipping, I occasionally run into a system error that lasts the whole day. Inevitably this is always on a Monday afternoon and I am swapped with orders to ship. I have been using Priateship for years and never once had the app give me an error. Plus the support has always been quick to respond and always answered my questions. The only downside is that they don't support Amazon as a sales channel.....but hopefully that is something for the future.
