Walmart offers the RL Flo-Master 1-Gallon Economy Sprayer, model no. 1401, for $6.92. Opt for in-store pickup to dodge the $5.97 shipping fee. That's the lowest price we could find by $9 for a similar sprayer, although we saw it for $2 less last month. It features a poly wand and nozzle, adjustable spray pattern, and a pump handle.
