Walmart offers the Relaxzen 2-Motor Mid-Back Leather Office Massage Chair, model no. 606814, for $55 plus $9.97 for shipping. (Free Site-to-Store is also available.) That's the lowest total price we could find by $23, although we saw it for $6 less last summer. Sales tax is added where applicable. This chair features two vibration massage motors that operate with four AA batteries (not included).
