Your current account credit is displayed in the top left of your dashboard.
Once you submit an order, this credit will be available as a payment option, as long as you have enough credit on your account.
If you wish to use all available credit to submit it as a partial payment, our sales team can assist with this. For this please join us on our live chat, so they can apply your credit manually to your order.
For this and any other questions join us on our live chat on the bottom right.
