Our distributor, Lulu Enterprises (via POD print and ebooks), recently introduced an integration of their fulfillment service with Spotify, and have promised to do the same for WooCommerce soon. Both are attractive in their way but, for us, are pretty much a solution to a problem that does not exist.
And an added expense. The Arachis Press Store at Lulu's site works perfectly well and all our books are distributed to the various online retailers (including, of course, Amazon for those who prefer it). At least in theory, one can order print copies at local bookstores. So there are no plans to open up any other sort of store anytime soon.
