To input a coupon before placing your order, go on the checkout screen. Scroll down, and on the {bottom left/right-hand} corner there is a textbox “use a coupon” just before the total of your order. Enter your coupon code, then click on “submit” and you will see the reduced total! You can use the coupon FIRST10 to get 10% off your first order. Then proceed to checkout to initiate the payment and place your order!
