Products for a certain percent off

So I’m working on a game and have been asked to make a deals menu where you can sell products for a certain percent off, I was wondering if it’s possible to sell gamepasses with a discount, I know I could use a dev product but then people might end up buying both the deal and the main gamepass and I wouldn’t want that to happen.
Does anyone know if this is possible or a better way to do this?

Perhaps make multiple game passes at different prices, and have them all activate the same product.
