This way of ordering first and then refunding is risky, because in this process, you need to pay the cost of beads before you can get a refund. If you meet a bad merchant, there may be fraud, such as shoddy goods and delay in refunding money. This will harm your interests.

Therefore, it is recommended that you pay attention to the following points when choosing this method:

1. Try to choose merchants with high credibility and good reputation, and you can check their evaluation and historical transaction records.

2. Make clear the specific requirements, specifications and prices of beads with the merchants before placing an order, and sign a contract or agreement to ensure their rights and interests;

3. After receiving the beads, carefully check the quality. If there is any problem, feedback it to the merchant in time and keep relevant evidence;

4. In the transaction process, we should pay attention to protecting personal privacy and information security, and avoid revealing personal information or funds.

If you don't feel comfortable with this transaction method, you can choose other safer transaction methods, such as network platform and third-party guarantee. At the same time, we should also pay attention to preventing security problems such as online fraud.
