I used to hate entering promo codes, but now many sites apply them automatically. Using the [magento 2 ajax login popup](https://amasty.com/exit-intent-popup-for-magento-2.html) extension makes it even better, and it finds and applies the maximum possible discounts without making me lift a finger. Combine this with modern quick checkout systems, and you'll feel like the days of tedious multi-step online shopping are long gone. Now everything happens naturally.
