I have gotten most of my cutting dies on www.shoppersrule.com you make a bid on what you want to pay and they will tell you if they except the price or not. and if they don't they give you the price that they well except. also they have the dies on sale quite a bit at 30% off. I just order the new dog & cat dies that are for the baby go but you can use them on the regular go and they were $14.00.
Love the machine it is fun to use and does a great job.
