A customer encountered a problem configuring the Zone Table Rate Shipping module in osCommerce. While the module worked well for enabling various shipping methods across multiple zones and weight bands, issues arose when combining Weight + Price restrictions. Specifically, they noticed that:
- Shipping methods remained visible and selectable even when the cart total exceeded the configured price threshold (e.g., £20).
- They needed to restrict certain methods based on the cart price and weight to match compensation limits offered by specific shipping services.
The customer sought clarification on whether weight overrides price, if this behavior was a bug, or if they had misconfigured the settings.
The team suggested adding an additional price line to the configuration to properly handle price cutoffs. This adjustment ensured that shipping methods would no longer show when the shopping cart value exceeded the defined limit.
By implementing the suggested solution, the customer successfully configured their Zone Table Rate Shipping module to account for price cutoffs. They added a secondary price line (e.g., 20 to 9999 with a negative cost adjustment) to remove handling charges for certain shipping methods like Royal Mail Second Class.
The result? A seamless shopping experience for customers, with clear and accurate shipping options tailored to cart value and weight, preventing confusion and ensuring compliance with compensation limits.
