Sensodyne - Cheap Anywhere?

Might be a weird one but my preferred choice of toothpaste is Sensodyne but I am too cheap and refuse to pay $10-12 a tube from Safeway. They do go on 50% off sale like once every leapyear it seems. I've ran out and have to resort to using Oral-B like a peasant (joke) and its just not the same. It probably is no different whatsoever in terms of cleaning my teeth, nonetheless I want my sensodyne.

Anyone else crazy like me and want to use a specific brand of toothpaste? Also, anywhere I can get it cheap?
