Staples offers the Microsoft Comfort Curve Keyboard 2000, model no. B2L-00002, for $9.90. Choose free ship-to-store pickup to avoid the $9.95 shipping charge. That's tied with our mention from a month ago and $6 under the lowest total price we could find elsewhere. Sales tax is added where applicable. Features include a spill-resistant design, media keys, and both USB and PS/2 connectivity.
