How can I apply a 30% discount on the 2nd item and 50% on the 3rd?

hey, how i can make a discount of 2nd item 30% off, 3rd item 50% off?

hey, thank you for the great answer! 

but maybe i didnt made it clear enough, the discount is on all the site (500 products), not on a specific product, so how the platform know that the 2nd item someone add to the cart gets 30% and the 3rd gets 50%?

when i add the 2nd item i need it to reduce by 30% and the 3rd needs to reduce by 50%

I'm not aware of any app that can do this out of the box.

Your best bet is probably to build a custom automatic discount app with Shopify Functions, though that's Plus only.
