My 2 cents...on the one hand I also don't feel okay asking more than the issued price + the extra costs for shipping, but on the other hand there are lots of books I'd like to add to my collection for which I also need to pay a premium. The bit of profit I can make this time (opportunities like this don't happen too often) allows me to add some other books to my collection which cost a lot more than the issue price. Isn't that the way most of us collectors like to build their collection?
