Walmart has often been named the cheapest store for patio chairs, but it has stiff competition. That includes Ikea, Amazon, discount warehouse stores, thrift stores, Big Lots, and other discount places. Rather than focus on the cheapest store to shop at, I recommend setting your budget. Set your search and filters based on your budget, and comparison shop. Just because something’s available at one store doesn’t mean that it’s guaranteed to be cheaper. While Walmart does sell cheap patio chairs, I’ve seen deals elsewhere.
