Newegg.ca: Keyboard For $15 & Free Shipping
Newegg.ca is offering a good deal on this basic Microsoft keyboard. The Microsoft ANB-00001 USB Wired Slim Keyboard 600 is only $14.99.
I'm posting this up as it's a decent price, especially with the free shipping.
I actually use a wireless keyboard and mouse on my home computer. I do have a back-up wired keyboard in storage though, just in case. If anything happens to my main keyboard, I'll be sure to have a spare for emergencies.
