In my Google Product feed I have both Visa and MasterCard listed as accepted payment methods. Is it possible, and is there any benefit, in adding the remainder of my payment options; American Express, Delta, Maestro etc.        <g:payment_accepted>Visa</g:payment_accepted>        <g:payment_accepted>MasterCard</g:payment_accepted>I can't find anything in the specification that mentions the payment methods.My feed applies to the UK, US and EU.
Add multiple payment options in Google Product feed XML

It would seem that there are little to no ranking benefits from adding a bunch of extra payment options to the <g:payment_accepted> node.
