With orders of $25 or more, Amazon offers the Summer Infant Pacifier Thermometer in Teal/White, model no. 14514, for $3.74 with free shipping. (Non-members can spend $35 to bag free shipping.) That's a buck under last week's mention and the lowest total price we've seen. (It's the best deal now by $4.) It features a fever alert and remembers the child's previous temperature.

Note that this item is part of Amazon's "add-on program" and can only be purchased with an order of $25 or more.
