Spree extension for adding zipcodes to zones
Based off of extension spree-city-zones: https://github.com/niamtech/spree-city-zones.git
Adds ability to create zones based on zipcodes instead of cities.
bundle install
bundle exec rake spree_zipcode_zones:install
bundle exec rake db:migrate
Then you can add zipcodes like states, and associate them into zones. Does not support city/state inheritance.
