Growave discount codes being used on already discounted items - how do I stop this?

hi all. I currently use Growave as a loyalty club for my customers. When they reach a certain number of loyalty points they are issued with a discount code which can be used at checkout. However this is discounting the entire order. I would like the discount to be on full price items and not on items that are already on sale. Is there a way of doing this? Thanks for your help

If you haven’t, You can contact Growave.

But, there is an option in the settings to limit the discounts to specific collections. It’s not the ideal solution as if you a single product that appears in a collection that is allowed to have a discount and one that is not allowed to have a discount It will allow the discount.

I have a product line that I am not allowed to discount ever. It works well and discounts are applied to other products within that order, and I’m fine with that. The customer’s going to get a discount on a non-discounted item eventually. Fortunately I have enough different items of the same item type that people will want things that are both discounted and not discounted.
