I often buy the ones on special however I do not understand why McLeans is so much cheaper than Colgate apart from the fact that they are possibly a much smaller company.
I have therefore bought McLeans several times, and I do not go out of my way to get one without fluoride as since they put this in water and toothpaste, I have had about one filling in many, many years. As a child I had my whole back teeth filled and still have many of these original fillings.
So, I do not buy the same brand of toothpaste each time.
No,I do not use the same one all the time! Like most things,variety is the spice of life!!! I like mcLeans,and I used to use Ipana some years back. Colgate can be very expensive and when it is cheap I worry where it has been made. Parallel Imports usually are made in China or Indonesia.
I usually buy the toothpaste that is on special at the time. So I've tried many different brands, including Colgate, McLeans, Redseal and Whiteglow and 'Darlie' (an asian brand from Hong Kong). But I prefer a very minty toothpaste!
