If you include data in the "shipping-price" field in your feed, this information will override any rules you have created.

• Make sure that you do not have two or more rules that apply to the same product. If this is the case, the shipping price displayed will be the sum of all applicable rules. Make sure you have given enough time for your rules to be reflected on Yahoo! Shopping. It may take up to 24 hours following any rule or product feed updates for changes to take effect.
• If your rules depend on product feed data, please make sure that your feed has been accepted and is formatted correctly.
• Make sure the status of the applicable rule is "On."
