Not so much a discount but still a bargain buy.
I have Grinders capsule machine that uses Caffitaly type pods and have tried a number of different ones since I got the machine.
Each has their own tastes, but the only one I kind of like at the moment is Grinders own capsules - Crema and Double espresso, which are on special BTW - $5.50 for 10.
I tried most pods there are. Urban brew and expressi are drinkable but only if you have nothing else. And please, do not get the St Remio ones
Decided to try Coles Urban Coffee culture and I think its a bargain! $3.70 and taste pretty much the same as Grinders. Packed at the same factory too =) #10 is a bit weak tasting but #12 and #14 are spot on.
Not really comparing proper espresso with pods, but Caffitaly has twice as much coffee in a pod in comparison to Nespresso. Just saying
