Vyntic Metal Sync - Live Metal Rates for WooCommerce

Vyntic Metal Sync is a WooCommerce precious-metal pricing plugin for stores that sell Gold, Silver, Platinum and Palladium products. It retrieves current metal rates through the managed Metal Sync Live Server and can automatically calculate eligible WooCommerce product and variation prices using material weight, purity, making charges and markup. If the live-rate service is unavailable, administrators can use manual fallback metal rates so product pricing can continue without depending on a successful live request.
