I bought a keyboard and mouse combo from Costco. I thought it is a good deal. $29.00 plus ECO Fee 0.5 , plus tax. Some store price it at $66.77 plus shipping.
Logitech MK345 Comfort Keyboard and Mouse Combo / Logitech MK345 Wireless Desktop Keyboard and Mouse.
- Full-size Keyboard.
- Mouse in good size. Not a compact one.
- Batteries are pre-installed.
- Keyboard battery life is 36months. 2 X AAA batteries. ( Based on the support website, it is said 48 months, or 4 years. But I think 36 months is more conservative.)
- Mouse Battery life is 18 months. 1 X AA battery.
