If Amazon is a wholesale model, 20-30 products a day is enough, but each company is different, so it still depends on the company's requirements. If it is a boutique store, it doesn't matter how many products are put on shelves in a day, because the focus is on the operation of the store, not the goods. Boutique stores only need to maintain a total of dozens of products.

So the number of products Amazon puts on shelves in a day is actually not very important for the operation of the store. And it also needs to be determined according to the store's business model.
