Hello and sorry for the super late reply but I’ve missed your post somehow.
Thank you for purchasing NodeCanvas Lite. Since you already own Lite, a discount is already applied for you when you add Full version into your Unity Asset Store cart. Please note however that this discount is not combined with any other discount like for example Black Friday or Christmas sales on the Asset Store (this decision is beyond publishers control and only decided by how the Asset Store operates).
