Opt for in-store pickup to avoid shipping fees

This RL Flo-Master 1-gallon sprayer is only $4 at Walmart right now. Shipping adds an additional $5.99 unless you order $35 or more from the mega-retailer. You can also choose free in-store pickup. That’s a fantastic price on a one-gallon sprayer! And these sprayers are perfect for doing your own pest control which can easily save you hundreds of dollars over the years with just a tiny up-front investment.
