Well you will need to tag your content for preferences. On account creation
you do a questionnaire. So that is now in a database. The you tie your app
into the location services. That would ping back and everything in "range"
would be tagged and made available in the apps offer screen. With a single
notification of offers in your area. I would not suggest using another
service as your transport as that can get your Data banned.
