Walmart offers the Viking Foaming Soap Spray Nozzle for $9.99. Opt for in-store pickup to avoid the $5.99 shipping and drop the price to $9.74. That's $2 less than our mention from last July and the best deal we've seen. (It's the lowest price now by $17.) It features three spraying modes and holds up to 7-oz. of liquid car soap.
