Walmart offers the Mainstays Vinyl and Mesh Task Chair in Black for $33.70. (Several other colors are available for $34.88) Pad your order over $35 to bag free shipping; otherwise, shipping adds $5.99. (In-store pickup is also available.) That's tied with our mention from three weeks ago and it's the best price we could find by $4. It features 1-touch pneumatic height adjustment.
