Just giving this a bump since this sale ends in a couple of days, on July 31. I myself have been putting off looking at the Edith Layton titles (25% off on most/all, as Avice mentioned upthread) and just realized that I only have a couple of more days to do so.
Also, once before, Smashwords sale coupon codes started acting weird on the last day - I could use them but the "Buy with Coupon" button quit working so I had to add the coupons by hand, which was a minor pain. So maybe it's best not to run up right against the end of the sale

.
Anyway, here's the bump...
