How do I enter a coupon on the Matalan website?

[Candycanestripes]

I got emailed a voucher code for the Matalan site. I have got all the way to the checkout and there’s no option for a voucher code - only a gift card with pin which I don’t have! Can anyone help?

This drove me mad a few weeks ago. You have to go to your shopping bag and enter it there before you check-out, I think.
