Just taking a very brief look at this and it seems like a great idea! They've basically "unbundled" something like Shopify and are selling the individual parts (embeded Buy Now button, data export, etc.) separately for a monthly fee. It does seem like adding all the separate fees together could cost more than Shopify for some small stores, though.
