Not yet. But shipping is always expensive unfortunately. The pamphlet + pdf price I have is 5 bucks from the TKG store, but then it's showing 15 bucks for shipping (I'm international, so it might be more for me).
If TKG is charging you 5+4.50 for the pamphlet, that's probably decent pricing. That said I definitely understand the frustration of seeing shipping be close to or more than the price of the actual product.
TKG paid me for a certain number of copies for their store, so unfortunately I don't have control of what they charge for it.
Looking at eventually setting this up for PoD via DrivethruRPG but there are still some kinks to work out. Shipping costs will likely be similar.
