Pop-up when selecting multiple variants

[ariebakker]

To minimize return shipments I want to show a pop-up message when customers add 2 sizes of the same product to their chart. Someone knows a good Shopify App of flow for that?

Hi, @ariebakker. I don't know of a specific third party app that would work best for you, but you can find a list of popular pop up apps in the app store here.
