Thought I'd share:

While looking for PreviDent5000, I came across 3M Clinpro5000.
I noticed the 3M version was more than double the size and they were both $13.99 (I live in Canada, no Rx required, on the shelf).

For whatever reason, it rang in on sale at $3.50, ShoppersDrugMart.

It also looks like it has some advantages over the Colgate brand too, including the remineralizing agent Tri-Calcium Phosphate:

Anyways, hope it's available wherever you are if you're interested.
