Sam's Club vs. Costco: Store brand match-up - Yahoo

I wonder if this is still the case?

"Food
Costco’s only generic line “Kirkland Signature” offers an array of high quality choices at affordable prices. Sam’s Club, on the other hand, is a “club of many brands.” From its original core generic label “Member's Mark,” Sam’s Club has expanded to now offer category-specific private brands such as Artisan Fresh, Daily Chef and Simply Right, to name a few.

Finding apples to apples comparisons was difficult and sales are constantly changing but we did find these head to head comparisons. 

Sam’s Artisan Fresh Chicken Salad goes for $4.78 per pound, a little bit cheaper than Costco’s Kirkland brand for $4.99 per pound.

If you’re shopping for boneless, skinless chicken breast Sam’s Club offers a 12-pack for a $1.99 per pound. At Costco, as 12-pack of the Kirkland signature fridge-to-freezer chicken breast goes for $2.99 a pound.
