### English: 2. If it is not the quality problem of the product itself, the buyer needs to return or exchange the product due to the buyer selecting the wrong model and other factors. If the product's own functions are not affected or will not affect the secondary sales, our store supports free return and exchange services except the freight charges. The shipping cost needs to be borne by the purchasers.
### Errors: There is a minor error at "is not the". There is a minor error at "problem". There is a minor error at "will". There is a minor error at "secondary sales". There is a minor error at "except". There is a minor error at "rs".

### Improved English: 2. If you need to exchange or return the products due to reasons other than the quality of the product itself, such as the buyer choosing the wrong model or other factors, our store supports free exchange and return services under the condition that the function of the products or a second sale is not affected, and the shipping fee back and forth shall be borne by the buyer.
