Can I use discount codes during a sale?

During sales it's possible to use only personal discount codes with a specific amount. If you have a percentage discount code, it's not possible to use it during sales. It's not possible to use our 15% promotional codes during sales. If we give special percentage discount codes, it's not possible to use them on sale products. If you have sale product(s) in your cart, it's not possible to use special percentage discount codes.
