Ohbuybuybuy via eBay offers the Soapy Stainless Steel Hands-Free Automatic Liquid Soap Dispenser for $8.33 with free shipping. That's a slight drop from our November mention and the lowest total price we've seen. (Outside of other eBay sellers, it's also $2 under the best deal we could find for a similar dispenser elsewhere.) It features a 9.5-fl-oz. capacity and requires four AAA batteries (not included).
