Yes.
With Ongoing you can offer free shipping specifically for subscription products, this means free shipping on all recurring orders.
Alternatively, Shopify Discounts allows you to make a discount code that applies to subscription products that only applies for a temporary time (think promotions!)
2 ways to Offer Free Shipping on Subscription Products:
offer free shipping on a subscription product for a flash sale (not forever) ( discount code tutorial)
offer free shipping on a subscription product forever (all the time) ( includes a video! )
It goes without saying Ongoing Subscriptions is native for Shopify (Build for Shopify) and works automatically with Shopify discounts, so no extra steps needed!
Ongoing subscriptions automatically syncs with Shopify Discounts.
