A system and method for performing a handover operation in a broadband wireless access communication system. The system includes an indicator positioned proximate a retail display of a discounted product. Coverage metric Ck,t is monotonic non-increasing in k and monotonic non-decreasing in t, allowing for a divide-and-conquer search strategy to be used to find the critical threshold pairs. A selected length of the material can be separated from the roll by pressing the material against the cutting edge and pulling the length of material thereby cutting the material in a linear fashion.
