Can free shipping be applied to select subscription groups in Bold Subscriptions?
Is it possible to offer free shipping on only some subscription groups, not all of them, within the Bold Subscriptions app?
No, there isn't a feature within Bold Subscriptions to set free shipping for specific subscription groups. Free shipping can be set up for specific products within the Shopify shipping profile, but this will not automatically update existing subscribers.
As a workaround for existing subscribers, you can make a temporary change in your customer's account which will cause Bold Subscriptions to look for a new shipping rate. For example, you could update the quantity of the customer's subscription product, then revert this change so the correct information is stored along with the new shipping rate.
Pro-tip: If you would like to create fixed shipping rates in Bold Subscriptions, you can update all existing subscribers shipping rates at the same time. For more information, please visit Fixed Shipping Rates in Subscriptions for Shopify Checkout.
