The it'seeze webshop allows you to setup discount codes that can be used by your clients at the checkout to get a % or fixed amount off their order.
It's a very useful tool to help drive traffic to your webshop as everyone loves a discount or special offer.
For example just before fathers day you might setup the discount code called FATHER2020, then you might share this over social media, on your website and via a news letter to help attract visitors back to your website shop.
