PowerBlock review for Intuitive Shipping

Jan. 26, 2026

This app solves a critical issue for us with calculating accurate rates because our dumbbells ship in multiple boxes and contain multiple items. We're able to manage the multiple items and dimensions accurately, resulting in incredibly accurate shipping rates between what customers pay and what FedEx charges our business. The Shopify native solution for FedEx is only weight based which leads to large discrepancies on large qty and line item orders. Intuitive Shipping eliminates this problem. The app works great, and I'm able to quickly import and export data needed to set product dimensions easily.
