More from the e-reader wars: Target has confirmed that it will begin selling the Kindle in all its 1,740 stores starting this Sunday, making it the first brick-and-mortar retailer to carry the e-reading device. Target senior v-p Mark Schindele said Target customers' response to Kindle "has been overwhelmingly positive." Not to be outdone, Barnes & Noble today announced a promotion that offers a free $50 B&N gift card with a purchase of the $259 Nook. The certificate can be used toward any material that can be used on the Nook.
