@Kim Reirson will most likely have a more detailed answer, but within the 'Trigger' of the Flow, there is an option to create 'Profile Filters' where you can limit the flow to only certain profiles. This is where you can create a filter that excludes the people who have Ordered a specific product! I'd probably do the Profile filter 'What someone has done (or not done)' Person has 'Ordered Product' then select the little filter icon, and choose property (you could do the name of the product, the sku, the variant name, etc.), 'zero times' 'since starting this flow'. That should stop people who have bought that specific product from entering your flow or once they are in the flow to be removed once they've purchased that specific product. It's a lot like the Abandoned Checkout flow where you exclude people who have purchased since starting the flow. Hopefully that helps! I've screenshotted where you'll find these two pieces as well.

@Mariana Córdova You're welcome!
