A inverted version of the products rule that comes with Spree. This rule matches all products that are NOT marked for exclusion. Excluding the product is done by a checkmark on the productpage.
Combine this with spree-promotion-roles-rule and you can create a discount for a special group of customers on all but a few selected products.
Add spree_promotion_exclude_specials_rule to your Gemfile:
gem 'spree_promotion_exclude_specials_rule', github: 'traels/spree-promotion-exclude-specials-rule'Bundle your dependencies and run the installation generator:
bundle
bundle exec rails g spree_promotion_exclude_specials_rule:installAdd rule to config/initializers/spree.rb
