Let's say I make 50% in profit from each plush (https://chat.openai.com/share/5219bcf8-5997-4a28-80b0-3d73546cdfb9).

I'd make a 50% discount for next two pushes, for you.

From my perspective, then, you've bought 2 plushies at their original price (while really you got 3 with a discount). I sold 3 plushies for the price of 2 and still profited from the 1st one.
