I just received this today and asked my neighbors for their copies and googled it for information. This is basically all the sunday ads bundles with coupon inserts for free along with a 5-6 page paper listing some popular sale items.

Here's the fine print from their website. Oddly enough I didn't find this through MiamiHerald.com but only after googling for it.

Your Yes! package may include these retail inserts and others, and may vary week to week. Yes! will be delivered each Sunday by 9 AM. Yes! is available in the following ZIP Codes and only to households not subscribed to The Miami Herald/El Nuevo Herald: 33155, 33160, 33162, 33165, 33172, 33173, 33174, 33175, 33176, 33179, 33180, 33183, 33185, 33186, 33193 and 33196.
