You can go to the consumer association to report the gross profit margin of the product, if the product is the same as you said. If they are all the same product, the store will make a profit. You can also apply for a return if you don't use it. If you use it, I suggest you buy a copy online. Then package it in his long-term packaging. Call the Consumer Association and sue him. Apply for a return! It's that simple! Manually typed, please accept.
