Agreed on the first point, however the common thing of storefronts like ours is that they start with digital goods, then tack in physical products, email marketing, affiliate marketing, and so on. All on the same interface.

Stripe and SellApp go hand in hand. Where Stripe is a payment processor, SellApp is the storefront that takes care of the pre-sales and after-sales process including product delivery, security, order replacement, etc.

That said, Stripe does seem to have recently launched a new product known as "Payment Links" which may eventually grow out to something similar to SellApp.
