Not sure where your pricing comes from. Official Verizon pricing has the two phones at the same price.

In our area, a store is lucky to sell through their initial order of Spectrum models (usually a case of ten) over the past six months. The Rezound has sold at about a case per week. I haven't had major problems with the Spectrum, I just think most people would rather buy something other than an LG smartphone. Much of that seems to come from one of four lower-end "beginner" Android phones they've put out over the past couple years.
