I also bought the Pro Pack (to use it with Exchange) but that was a big mistake. Buggy, and no refund unfortunately. That was an expensive lesson. Exchange itself has got very few options. I think five years ago this would have been a good solution for an e-store. But now it isn't.

iThemes does an acceptable job, basic features are working, more or less. Some problems include: misplaced coma in the shipping cost in the screen after the client confirms and emails notifications. This does not affect totals but is annoying. Localization a problem. Translation option are limited. Must re-upload my translation files every time I update the plgin. Slow Slow slow. It's slowing down my website, even with just basic features. Considering alternatives.
