@tarrell, @TazMan2000 when there's no site wide sale events like at the moment of this writing, then any discount you see is loyalty program discount. If you add such model in your shopping cart, you should see loyalty discount points automatically deducted from the price.
I don't see piggy bank icon either, except in similar models as it is mentioned by TazMan, this could be yet another UI issue, but the discounts themselves should work correctly. If that's not the case, then you should contact the support, as it's not something that site users could help you with.
