I just redid the store for Goddess Light website.  Shelly sells downloadable meditations and cd’s as well as classes and workshops and private sessions.  We thought it would be a good idea to redo the store using WP EStore plugin because it has many extended features such as pay per view, coupons, and pay what you want that is included in the software.  Other e-commerce software solutions have extensions that you need to pay a hefty amount for the added functionality.  Plus, as a designer, I like the flexibility of adding a pay button to any website page I designed rather than being forced to use a pre-designed template (and usually an ugly template at that).   Doesn’t it look nice and functional?
