Description

Stop losing sales to high shipping costs: offer fair Lettermail rates for small items.

High shipping rates kill conversions for small items. But standard Shopify settings double-charge customers by stacking Lettermail and Parcel rates at checkout, leading to even more abandoned carts. FixShip solves this instantly. Tag your lightweight products, and our logic does the rest: Lettermail pricing appears only when the entire cart is eligible. If a parcel-sized item is added, the Lettermail rate vanishes. Save your margins and your customers' experience. Improve conversions today!

Smart Rate Hiding: Lettermail rates available only if all cart items eligible
Fast setup: Add lettermail rates & product tags and you're set
Non-intrusive: Shopify-native performance invisible to customers
Zero-conflict logic: No stacking of shipping costs for mixed carts
