Looking forward to the amazon add-on. As of now, so far so good!

Additional edit in November:
I am not into e-commerce, but the app contains VALUABLE data regarding shopify stores!!! That's really a major plus that enables you to use the data for other purpose (cold calling shops to offer SEO or other services) or simply following trends of what works and what doesn't work in certains countries. I've got the tier1 as it is sufficient for my use case, and I feel I got access to a whole wealth of information!!
