Walmart offers the Cosco Simple Fold Full Size High Chair in several colors (Stencils pictured) for $34.88. Pad your order over $35 to bag free shipping. (Alternatively, opt for in-store pickup; shipping adds $5.99.) That's the best price we could find by $5. It features a 3-position adjustable tray and cup holder.
With these companies, it might be easier than you think to negotiate your monthly bill down.
