Whiplash Merchandising items API
Items are probably the most fundamental entity in the Whiplash system. An item is simply a 'shippable unit'. So, it's not a Whiplash T-Shirt; it's a Small Whiplash T-Shirt, for instance. Most commerce platforms model Products. Typically, however, a Product (e.g. a T-Shirt) has variations (named variously, Variants, ProductOptions, OptionSets, etc). An Item maps to the Variant/Option, not the Product.
