Equate is an example of the strength of Walmart's private label store brand. In a 2006 study, The Hartman Group marketing research firm issued a report which found that "Five of the top 10 "likely to purchase" private label brands are managed by Walmart including: Great Value, Equate, Sam's Choice, Walmart, and Member's Mark (Sam's Club), per the study." The report further noted that "...we are struck by the magnitude of mind-share Walmart appears to hold in shoppers' minds when it comes to awareness of private label brands and retailers." In mid-2010, the brand underwent a logo redesign, as well as packaging changes similar to the Great Value brand.

Pentobarbital was found in 5 out of the 8 Ol' Roy samples in the initial survey. The highest level of pentobarbital detected among all dog foods tested was an Ol' Roy formulation (Puppy Formula, Chicken and Rice) at 32ppb. The CVM concluded this level of pentobarbital would be unlikely to cause adverse effects even to the smallest dogs.

Parent's Choice Parent's Choice is Walmart's store brand; including diapers, formula, and accessories. Like other Walmart store brands, its design and packaging was relaunched in 2010. Parent's Choice is manufactured by Wyeth, a pharmaceutical company that is a subsidiary of Pfizer. On October 15, 2009, representatives of Pfizer signed the final acquisition papers, making Wyeth a wholly owned subsidiary of that company, thus completing
