Is it safe to enter my payment details on my mobile?
If you are an existing customer, M&S Mobile will use your default account payment method to place your order so there's no need to enter payment details again, unless you want to change them.
If you are a new customer, your payment details are automatically encrypted when you enter them - it’s just like ordering on our full website.
