Their is a way, however it is very time consuming. Kohls direct serach national wide which yeild a corporate division and then from their a seach by control point and county. However, seraching a set ranage will be easier or checking into a website that lists typical frequencies used nation wide. Usually their pretty acurate except for the pl / dpl code.
Many models of radios commonly used in retail stores (Moto XTN, CLS, etc) utilize freqs selected from a pre-programmed pool of 27 VHF and 56 UHF frequencies. You'll find a list of those common frequecies at http://www.walkytalky.com/Programming/Programming_XTN.htm . I'd start by looking at the UHF freqs, as I found sales folks at Kohls' Elmhurst store using one of the above-mentioned radios on 467.875(82.5) in August 2005. Someone on the CARMA Yahoogroup http://groups.yahoo.com/group/carmachicago/ found 466.3375 in use at their Batavia store use back in July 2005.
FWIW, I've found that stores with loss prevention officers typically utilize separate freqs for sales floor, stock room and loss prevention operations.
