Doesn't work. I had to setup a 100% discount code and a free shipping code for a social media company I work with to test their code.
They couldn't get the codes to work.
I set up different codes twice. But still no joy.
So, this doesn't work. Hence 1 star. Zero stars really as it doesn't do the sole thing everyone is installing it for.
SIDE NOTE - Shopify. Hellooooo? Why is it still not possible to combine codes out of the box? Merchants have been requesting this for YEARS and you keep ignoring them. It is frankly shameful that anyone would even need an add-on paid app for something as simple as this.
