Auto parts are a professional business, and the accessories of various models are different. If you can't guarantee a single market, the risk of buying and selling your own goods is inevitable. If you don't know what to sell and what customers want, you will waste a lot of resources.

Your idea is very good. I suggest that you can fry melon seeds and nuts first, which can also be understood as futures. The market is your warehouse, and now there is no shortage of roasted seeds and nuts in the auto parts industry. That is, if you don't purchase the goods yourself, contact the wholesaler to sell them now. If you are in an online shop, you can post some pictures of various accessories for publicity. Guests can say whatever they want. You can contact them here. Solutions are people's ideas! It is best to have a familiar wholesaler.
