Master branch for Spree 3.3.0+ Read version notes for details.

This is a spree extension that solves two use cases related to variants. I call them Ad Hoc Options and Product Customizations.

Ad Hoc Options

Use these when have numerous (possibly price-altering) product options and you don't want to create variants for each combination.

You can also restrict certain combinations of options from coexisting. These are called Ad Hoc Exclusions.

Product Customizations

Use these when you want the ability to provide a highly customized product e.g. Cut to length 5.82cm, Engrave 'thanks for the memories', Upload my image. Full control over pricing is provided by the Spree calculator mechanism.
