The answer to this question depends on a number of factors, including the type of product, the market it is selling in, the time of year, and more. That said, there are some general categories of products that tend to sell faster than others. For example, items that are associated with a current trend or fad tend to sell quickly, as do items that are new to the market and/or in high demand. Additionally, products that are priced lower than similar items tend to sell more quickly, as do items that are seen as essential or necessary (such as food or medication).
