Finicky maybe glitchy
Had trouble with entering the 49THAPP10 discount AND ship to store AND using Apple Pay. The payment (Checkout or Apple Pay) show up immediately. But you need to enter the discount code, shipping options BEFORE you hit Apple Pay. Otherwise Apple Pay defaults to shipping and doesn’t include discount. App developers: you need to GREY OUT the Checkout and Apple Pay buttons until user scrolls through to the bottom of the payment page. Only allow the selection AFTER all fields (discount code, shipping option) reviewed and entered.
