Walmart, the parent company of Sam's Club, is responsible for the manufacture of the Member's Mark brand. Walmart is a worldwide retailer that generates billions of dollars in revenue every year, and it's no surprise that it has the capacity to manufacture the products in-house.

Whether you're looking for everyday shoes and clothes or a sparkly piece of jewelry to add to your look, Sam's Club has it. Shop for sizes ranging from newborn to adults, and everything in-between. And when you shop for clothing, jewelry and shoes at Sam's Club, you'll always enjoy members-only prices.

Sam's Club wins the price comparison battle, but with some important caveats. The warehouse store typically sells items in bulk or, at the very least, in larger sizes than you would find in a typical package at a regular retail store like Walmart.

Costco's membership fees are more expensive and the prices of basic products at Sam's Club are generally cheaper. Costco has more stores worldwide, but Sam's Club has more stores in the U.S. Costco has a larger store foot print in terms of total square footage.
