# This class is responsible for selecting a price for a variant given certain pricing options.
# A variant can have multiple or even dynamic prices. The `price_for`
# method determines which price applies under the given circumstances.

class PriceSelector
# The pricing options represent "given circumstances" for a price: The currency
# we need and the country that the price applies to.
# Every price selector is designed to work with a particular set of pricing options
# embodied in it's pricing options class.
