SMART Shipping Rates & Rules ranks #1 for delivery-customizations-functions with 12.7% share — the leader position in a fragmented field where many apps are within striking distance, -9.2pp ahead of SMART Bundles Volume Discounts (21.9%). Blockify Checkout Customizer sits at #3 with 5.3% share, rounding out the top tier.
