Advanced Electronics via eBay offers the Philips Sonicare HX6013 ProResults Standard Tooth Brush Head 3-Pack for $11.76 with free shipping. That's $3.92 per brush and tied with last week's mention as the lowest total price we've seen. (It's also a current low for this quantity by $2.) They feature a snap-on design and contoured bristles.
