Nine of the 15 retailers analyzed by Chicago-based market research firm Market Track showed they had fewer private label promotions in ad circulars last week than the same time a year earlier.

The research, done exclusively for PLBuyer’s eReport, showed Walmart had the largest decline from a year ago, with 27.5 percent fewer private label promotions. H-E-B (-24.5%) and A&P (-20.1%) also showed big drops.

On the positive side, Publix (+42.3%) and Rite-Aid (+35.8%) showed major gains.

Market Track’s analysis reflects regional versioning and market specific differences in circulars. This is accomplished through an extensive collections process, including physically obtaining the ads from the various markets in which they are distributed. In instances where retailers send additional circulars to a limited number of markets, Market Track’s information reflects these nuances to give a view of what is happening nationally.
