Cox Communications have expanded their relationship in several markets where Cox will bundle Verizon Wireless Services. According to a company announcement, customers in "select markets" in Kansas, Arkansas and Nebraska can now bundle Verizon Wireless services to receive gift cards ranging from $100 to $400 -- depending on the services selected. The two companies initially launched their endeavor in Oklahoma last May, on the heels of similar Verizon partnerships with Time Warner Cable and Comcast. Right now the relationships consist simply of gift card promotions, but Verizon and cable operators say they're working on way to integrate services across wired and wireless platforms.
