# Unexpected Shipping Costs

If a customer sees a shipping cost you did not expect, it is worth knowing where that number comes from. [Conditional Shipping for WooCommerce: Restrict Shipping Options by Anything](https://wpfactory.com/item/conditional-shipping-for-woocommerce/) only shows or hides your existing WooCommerce shipping methods. It does not calculate or change any shipping price, so an unexpected cost is set elsewhere.

### Symptom

The shipping cost at cart or checkout is higher or lower than you intended for a given order.

### Cause

Conditional Shipping decides *whether* a method appears, not *how much* it charges. The amount always comes from WooCommerce itself:

- The **shipping method and zone settings** in WooCommerce (for example the Flat rate cost, or Free shipping requirements).
- The **product weight and dimensions**, when a method calculates by weight or size.
- The **shipping class rates** configured on the method, when different classes carry different costs.

### Fix

1. **Check the method cost in the matching zone.** Go to WooCommerce > Settings > Shipping, open the zone that covers the customer address, and review the cost set on the method (for example the Flat rate amount or any per-class costs).
2. **Verify product weight and dimensions.** If a method calculates by weight or size, confirm the values on the product are accurate, since they feed the calculation.
3. **Review shipping class rates.** If the method sets different costs per shipping class, confirm each product is in the correct class and each class rate is what you intend.
4. **Confirm which method the customer is seeing.** Use **WPFactory > Conditional Shipping** (also reachable at **WooCommerce > Settings > Conditional Shipping**) to check which methods your conditions leave available, so you know exactly which method's price is being shown.

**Note:** because Conditional Shipping never edits a price, changing a condition will not change a shipping cost. To change the amount, edit the shipping method in WooCommerce.
