the nexus in not being sold at walmart. the site is from lets talk inc. they use the walmart name as a partner company. in other word...they pay walmart to use their name. the phone in no way is bought through walmart and odds are it will be more expensive then cheaper. don't say you KNOW it's going to be cheaper when truth is you (and I) have no idea. but again just remember, THIS IS NOT WALMART SELLING THE PHONE IT IS LETSTALK INC.
notice the site is not walmart.com
this is similar to the thing that happend with circuit city. after they went under a web site started using their name, logos, etc. they got them from circuit city. people thought it was the same company and it was not. it was a partnered up web site. prices were higher then the original company.
this stuff happens all the time.
