This from the Subpress website:
Here’s a special offer for those of you not out running around trying to squeeze one last vacation weekend out of the summer. Buy any two (no more, no less) in print SubPress books (no forthcoming titles, and the just published Promises to Keep by Charles de Lint is excluded) and the books are yours for 50% off. Regular shipping charges apply. Limited, Lettered, and Trade Editions are eligible for this special. So long as they’re in print (with the one exception noted above), they’re fair game.
You have until midnight tonight to take advantage of this special, so get to it!
