After purchasing goods on Alibaba, if you find that the price is more expensive than on Taobao, consumers have the right to apply for a refund of the price difference. The specific operation method is as follows:

1. Log in to the Alibaba website and enter "My Taobao": This is the first step to start applying for a refund of the price difference.

2. Find relevant orders: On the "My Taobao" page, consumers need to find relevant orders participating in promotional activities.

3. Apply for a refund of the price difference: Once the order is found, consumers can apply according to Alibaba's refund process. This usually involves filling out a refund application form and providing necessary supporting materials, such as promotional information at the time of purchase.

4. Wait for review and processing: After submitting the application, consumers need to wait for Alibaba's review and processing. If the application is successful, the price difference will be refunded to the consumer.

This process ensures that the rights and interests of consumers are protected when they find that the price they pay is higher than other platforms, and they can apply for a refund of the price difference through formal channels.
