Or at least why there has to be so many, many varieties.
I just nipped in to the supermarket to but some more toothpaste, usual brand (comes in a red box). It suddenly struck me as I was dithering over which one to get, how many choices there are and how impossible it is to know what distinguishes them all from each and which to get.
Just taking my usual brand as an example (also begins with a 'C') I counted no fewer than 17 different options with names that all seemed to be some permutation of "Total", "Advanced", "Whitening", "Sensitive" or "Fresh" together with the odd maverick variation like "Gel" or "Stripe". I mean can someone tell me what the actual difference is between "Total Whitening", "Advanced Whitening", "Total Advanced Whitening" and "Deep Clean Whitening"?
I can feel a letter to the manufacturers coming on!
And that is just one brans; the others all seemed to have many varieties to but to a lesser degree.
Does anyone know why?
