How many things do you actually buy repetitively?

So how many things do you normally buy that's the same exact brand and same exact item, for example the deodorant and shampoo and soap I have changes between brands and it's never really repeated constantly, so it made me wonder how many things do people really stick with one specific brand and keep getting the same thing, or do most people never really do that?
