Walmart offers the RL Flo-Master 1-Gallon Economy Sprayer for $4.89. Opt for in-store pickup to dodge the $5.99 shipping fee. That's tied with our mention from two weeks ago and the best deal we've seen. (It's also $5 less than the lowest price we could find for a similar item sold elsewhere.) It features a poly wand and nozzle, adjustable spray pattern, and a pump handle.
