In 2002, NHPA conducted its landmark Merchandising for Profit Study and then repeated it again in 2016. The purpose of the study was to quantify the sales lift generated by different merchandising techniques. The most recent iteration, the 2025 Merchandising for Profit Study, tested the effectiveness of a variety of merchandising techniques, including endcaps, dump bins (both permanent and manufacturer supplied), clip strips, bulk stack-out displays, countertop displays (for both service counters and checkout) and sidekick displays (also known as sidewinders).
