Buyer decision process

The buyer decision process is a series of steps that people go through when they decide to buy something. It starts with someone realizing that they need or want something. This might be something like: I am out of toothpaste and I need to buy more. The next step is researching what kind of toothpaste is available. After that, the person might compare different brands and decide which toothpaste to buy. Finally, the person will go to the store to buy the toothpaste or order it online. After the purchase, the person might evaluate how happy they are with their purchase and decide if they will buy that brand again.
