Needs ability to add multiple products to checkout.

Developer has corrected these issues with plugin and has reached out to me to correct any issues. Original 3 star review revised to 5 star.I can’t understand how the app was designed without this function, but if a customer wants to buy multiple items they cannot checkout and pay 1 shipping price for all, they have to pay shipping on every win.I take off 1 star for this function missing, and 1 star for developer insisting on charging for a function that really should be by default available as an option in the plugin.
