Costco memberships cost $55 annually for an individual or family.
"Regardless of family or home size, the consensus among the consumers we interviewed was that the membership fee to shop at Costco is worth every penny," Cheapism's Emily Lugg writes. "The purchase of one big-ticket item alone can recoup the $55 fee when Costco prices are set against those posted by specialty retail chains."
