I presume you're getting your hominy from Casa Iberica? Or is there somewhere else I should be looking for that kind of stuff?

I've been thinking of making a bulk-ish order of stuff from http://www.fireworksfoods.com.au/ since their prices are generally cheaper than CI. Not sure what their deal is with shipping (probably not too exorbitant since it's just from Sydney), but if you're interested in going in on an order, let me know.
