The offer price of a product, or of a price component when attached to PriceSpecification and its subtypes. Usage guidelines: - Use the [priceCurrency](https://schema.org/priceCurrency) property (with standard formats: [ISO 4217 currency format](http://en.wikipedia.org/wiki/ISO_4217), e.g. "USD"; [Ticker symbol](https://en.wikipedia.org/wiki/List_of_cryptocurrencies) for cryptocurrencies, e.g. "BTC"; well known names for [Local Exchange Trading Systems](https://en.wikipedia.org/wiki/Local_exchange_trading_system) (LETS) and other currency types, e.g. "Ithaca HOUR") instead of including [ambiguous symbols](http://en.wikipedia.org/wiki/Dollar_sign#Currencies_that_use_the_dollar_or_peso_sign) such as '$' in the value. - Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator. - Note that both [RDFa](http://www.w3.org/TR/xhtml-rdfa-primer/#using-the-content-attribute) and Microdata syntax allow the use of a "content=" attribute for publishing simple machine-readable values alongside more human-friendly formatting. - Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similar Unicode symbols.
