What i used to do was just buy one pack a fortnight when i did my shopping. (the huggies ones, the smallest pack which is about $14 if i remember?) Then it doesnt seem so bad, and when you get home from hossy, you will have a great stash. I also stocked up on dummies, wipes and other bits and pieces (the safeway/woolies wipes in a box are great - i think they are called select?? Its $20 for a box, and you get 6 packets inside. Works out pretty good, much cheaper than the huggies wipes)
