Can I use multiple vouchers on the one transaction?

Yes. On the bottom left of the checkout page you will see a box where the voucher code can be entered. Enter the code and click 'Apply'. The discount applied will appear and the total will be adjusted.

In the same voucher code box, a new field will appear, allowing you to enter another voucher code. Enter the code and click 'Apply'.

If you wish to remove one of the vouchers, simply click the cross icon.
