97 =head1 CONSTRUCTOR FIELDS
103 The price. A price of 0 is special and is considered undesirable. If passed as
104 part of C<available_prices> it will be filtered out. If returned as
105 C<best_price> or C<price_from_source> it will trigger a warning.
109 A unique string that can later be understood by the creating implementation.
110 Can be empty if the implementation only supports one price for a given
115 A localized short description of the origins of this price.
117 =item C<price_source>
119 A ref to the creating algorithm.
123 OPTIONAL. Prices may supply a numerical priority. Higher will trump lower, even when
124 supplying higher prices. Defaults to 3 (as in middle of 1-5).
128 OPTIONAL. Prices may flag themselves as editable. An editable price will still
129 be subject to checks for higher or lower prices, but will be rendered in a
130 fashion that allows the user to overwrite it.
132 This is potentially very distracting if the price is usually a default price
133 and will be changed in a lot of instances so use with caution.
135 On the other hand it can provide the capability that users unfamiliar with the
136 system will intuitively expect so it can be a good way to introduce the system.
140 OPTIONAL. Both indicator and localized message that the price with this spec
141 could not be reproduced and should be changed.
143 If price is missing, you do not need to supply anything except C<source>.
147 OPTIONAL. Both indicator and localized message that the conditions for this
148 price are no longer valid, and that the price should be changed.
150 If price is missing, you do not need to supply anything except C<source>.
154 OPTIONAL. Boolean indicator that this price was not computed for performance
155 reasons. This is only valid for PriceSources flagged as C<fast>. This price
