The warehouse club was the first choice of consumers in two regions, the Southwest and Southeast. Publix was a close runner up and H-E-B followed.

Costco also was consumers’ loyalty favorite among personal-care retailers, winning three regions and placing in the top three in the other two. Wal-Mart was the runner-up in this category. The highest-rated stand-alone pharmacist in this category was Rite-Aid.

In the mass-merchant category, Costco garnered most loyalty from bargain hunters nationwide. Target placed second, followed by Wal-Mart.
