Walmart.com has WEN 250-lb Capacity Rolling Mechanic Seat w/ Onboard Storage on sale for $12.24, after the $1.43 discount for store pickup. Otherwise, the price is $13.67 with free delivery over $35..
Amazon.com also has the seat for a price of $13.67, but as I am posting, there are only 8 in stock at Amazon. — OOS
I recently bought the seat and am pleased with it for garage work.
