Fast N Free

[*fselectronics]

I've got 2 items in the same seller location and the buyer can't reach fast N free for both of them, one is fast N free and the another one not at all. My shipping policy is 1 bussines day Handling time and UPS 2nd Day Air (2 bussines days). How can i get Fast N Free for both  in the same location?

Is one of the listings heavier than the other, and might possibly require an extra day in transit?
