You can count on Professor Dealzmodo to show you the best deals on the web, but what if you're looking for savings in your immediate proximity? That's when you pull out your iPhone and fire up The Dealmap app.
The app (which is free, naturally) aggregates sales, deals, discounts, and coupons in your city or town. You can see them scattered across a map or in a list view, which is sortable by type of discount or business.
You can also add deals you come across yourself to the database, earning status points to eventually become a Deals Hero. And between your daily session with the Professor and a league of deal heroes in your pocket, those are some pretty authoritative savings. [iTunes]
