I was having trouble with smashwords last night as it was showing a difference between the cart and paypal charges. I kept trying to update and it kept changing, so I gave up and went to checkout. Same problem as it showed an entirely different charge. I gave up backed up and left stuff in the cart.
I just went back and my "cart" is empty.
I went to get the link for the donate button on his site and noticed that he has changed the site again and the donate button is gone.
Why not buy a couple more of his? Penal Colony is supposed to be good and I liked Refuge. You can also choose to "buy" 2 copies in order to "pay" more.
