TomTop offers this Backlit 2.4GHz Wireless Keyboard with Touchpad for $5.99 with free shipping. That's about a buck under last month's mention of a similar keyboard and the lowest price we could find by $4. It features a 92-key keyboard, touchpad, and backlighting, and requires two AAA batteries (not included.)

Note: It ships from China and may take one to three weeks to arrive.
