Using WooCommerce with FedEx, USPS and per product shipping extensions. I need to have $0 shipping for two of my items, and the rest are to use the regular FedEx and USPS. Woo support directed me to purchase the per product shipping extension in order to get my "free" shipping on one item only but it's not working. This is way too much work to just have a single item where shipping isn't necessary......help? Anyone? Thanks!
