Information Priority
The new version of the promo message is right beside the price tag rather than on top of that. Users would not be distracted by how many remaining items are and then noticed the price is beyond their expectations.
Color Choice
Although a couple of e-commerce websites urge users to purchase with a discount or left stock messages and colored them bright red, we did not follow this strategy in this case. Bright red indicates users make some errors in our design system, so they will confuse about the effectiveness of the message. With only three choices left, we picked up muted magenta due to the low readability of the color yellow.

Product Carts Add On
I replaced the small size "Add to Cart" button with the checkbox to avoid a repetitive check out process. The label with "Save &250" is more recognizable than the wordy descriptions as displayed on the left hand.
Promo Message
Keep the same styling with product carts add-on component for being consistent. In terms of the mobile version, long description is changed to one line title and the image is fully displayed.
Alternative Products
Without reinventing the proper template for related products to fit in, I utilized the existing layout in our design system and it fits quite well for other product items.
Reflection
Next Step
Long reading will cause low conversion rate. Our team has to further discuss whether we would implant all of the old components into existing iRobot PDPs.
