Everyone has to manually search up their item when the sudden coupon codes appear which is a slower process.
Having potential items “watched” or “saved to cart” prior would help me and others instantly find the items so we can benefit from these limited coupons.
Hello @Gen_Wunner!
We appreciate you taking the time to give us this feedback.
We’ll make sure to pass along your suggestion to our specialized team so they’ll see what can be done.
Godspeed! 
Nothing can be done, the listing can be sold minutes later so it will be more painful when you get a new code like you gonna waste time looking at a cart with saved sold listings and you need to hurry searching all again
