Costco offers its members the Timber Ridge Folding Rocker Chair for $29.99 plus $2.99 for shipping. (Non-members pay an extra $1.50.) That's $22 below the lowest price we could find for a similar chair elsewhere. It includes a carry bag, padded armrests, and steel frame.
What's the most maddening fee you pay? To check your luggage? Bounce a check? Use an ATM? Not even close.
