At that price run and buy it.
As for dies go to eBay and buy bundles of dies. That is how I got 99% of my Go dies by buying bundles and bidding or offering a price of no more than 60% retail although I got most of them at 50% retail buying like that. I do the same for the mats. I find sellers with Best Offer and buy at least 10 mats of one kind at a time to get at least 40-45% off retail.
