The final price of the goods will depend on the actual test results. For example, there are no problems such as bumping and scratching during the use of the mobile phone. Before sending, the mobile phone status has been backed up with photos, but during the quality inspection, problems such as scratches on the screen or damage to the body are found. As a result, the words "no insurance, no return, no maintenance" were marked and the transaction was made at a lower price. When using salted fish to help sell services, we should carefully estimate the price. Read and confirm the relevant quality inspection results and final price before deciding whether to participate in the sales.
