The Rollout list, is a candidate list of all stores in the states that have been announced by the company (present and near future). It is not a list of actual stores provided by the company. The company provides me no inside, or any other, information. My approach is to perform rolling searches of all candidate stores, and update the map as I find stores that show it available in the store.
Majority of "keeping up" on this is through about 5000 lines of that dead PERL scripting language, coupled with a MySql database and Excel for charts.
