You can make use of distanceFromLocation: method of CLLocation.

distanceFromLocation:

Returns the distance (in meters) from the receiver’s location to the specified location.

• (CLLocationDistance)distanceFromLocation:(const CLLocation *)location

Parameters

location

The other location. 

Return Value

The distance (in meters) between the two locations. Discussion

This method measures the distance between the two locations by tracing a line between them that follows the curvature of the Earth. The resulting arc is a smooth curve and does not take into account specific altitude changes between the two locations.

Availability

Available in iOS 3.2 and later.

By using this method to get the distances of the shops with your current location, you can then sort the list based on the distance to get the nearest branch

VKS, I got to solve the exact same problem too now (using apptarget iOS 5). Do you have any example code / snippets / tips to share for this problem, that I assumed you solved a long time ago? The above is very good explanation from 7KV7, but some examples will speed up my process a lot. Thank's :-)
