SNIP: Structured Data & Schema Plugin for WordPress › Forums › Structured Data Help › Offer Shipping Details › Reply To: Offer Shipping Details
what do you mean exactly by “refreshing this”? The forum page?
If the forum doesn’t work for you, don’t hesitate to email support [at] wp-buddy.com.
When I google, the first thing I find is the Product schema on the documentation page: https://developers.google.com/search/docs/appearance/structured-data/product
The properties there should all be supported by SNIP if they’re listed on schema.org.
Doees that help?
