OfficeMax offers the Logitech M525 Cordless Optical Mouse in Blue, model no. 910-002698, for $14.99. Pad your order over $20 for free shipping; otherwise, shipping costs $7.95. Excluding the padding, that's $5 under the lowest total price we could find for this mouse in any color elsewhere, although we saw it for $5 less in September. Sales tax is added where applicable. This wireless mouse features a unifying receiver, micro-precision scroll wheel, ergonomic design, and more. It requires two AA batteries (included).
