The "WELCOME10" code is a discount reserved for first time buyers of IMAGE Skincare through our site. If you've used this code with a previous order you will not be able to apply it again.
This code cannot be stacked with other offers or promotions. Therefore, if you are already receiving a Free Gift With Purchase, or if a promotional discount has already been applied to your cart, you will not be able to apply the "WELCOME10" discount.
