Dear all: I just found out that Google is now correctly using gr:validThrough for price information: You MUST indicate a validity date that has not yet lapsed for gr:UnitPriceSpecification in order to be accepted as a valid price. <h1>Canon Offer</h1> <span about="#offer" typeof="gr:Offering"> <!-- Google-specific Review vocab --> <span rel="v:hasReview"> <span typeof="v:Review-aggregate"> Average rating: <span property="v:rating">4.4</span>, based on <span property="v:count">89</span> reviews </span><br /> </span> ... <span typeof="gr:UnitPriceSpecification"> <span property="gr:hasCurrency">USD</span> <span property="gr:hasCurrencyValue" datatype="xsd:float" content="899.00">$899.00</span> (Valid from : <span property="gr:validFrom" content="2009-12-30T23:59:59Z" datatype="xsd:dateTime">December 30, 2009, </span>through --->>>>> <span property="gr:validThrough" content="2014-12-30T23:59:59Z" datatype="xsd:dateTime">December 30, 2014</span>)<br /> <span rel="gr:valueAddedTaxIncluded" content="true" datatype="xsd:boolean">VAT included</span> </span><br /> This again shows that Google is increasing its support of GoodRelations.
