In terms of commodity wholesale: if you don't want to wholesale many commodities, you can choose to order online (of course, you should choose a reputable one). If you run a specialty store, then I suggest you visit it on the spot, which is more secure.
I'm a millionaire now, and I've joined the "upper class family", mainly dealing in fashionable women's clothes and parent-child clothes. At that time, I was also very ambivalent, worried that if the things I joined were not so good, the risk of doing business would be great. Then I went to several clothing companies to do some research. I was like a women's clothing company from the beginning. In several clothing companies I visited, I found that "upper class families" not only have women's clothing, but also have parent-child clothing. I thought it was good, so I joined this company. Now I'm doing well.
Now there will be more online scammers, so you should be careful. It is not easy to do business.
