Colgate don't seem to pay the fees required to have it at eye level at the supermarket... (Yes they charge companies for shelf position)
So - you usually find Nifti on the bottom shelf at Coles - I don't shop at IGA or Safeway so not sure about them?
+1 on the baby wipes - I buy the expensive ones as they are "tougher". (Handy to have in the car as well!)
For wax I use Mothers California Gold... Costs a friggin bomb, but it's good gear!
