Hi,
Please help us solve the above issue.

If you add a nonexistent Coupon Code, you receive proper notification message – “Coupon “DDF” does not exist! >>> But it shows only payment BANK TRANSFER method – the other payment methods does not show (e.g. Cash on delivery, etc.)

If you add the correct Coupon Code >>> the shipping (!) method disappears and corresponding message appears: There are no shipping methods available. Please double check your address, or contact us if you need any help..

best regards.
