MacUpdate has a daily promotion that features a single software program at a significant discount. Discounts seem to run between 40-50%, which is nothing to sneeze at... Recent featured software includes DEVONagent, which I touted in another thread on TS.
There is an e-mail alert option, but I have found that the alerts arrive a couple of days after the promo is announced. The largest discount is available on the first day of the promotion and gradually decreases, so I think that it is better to just check the Web site and see what is being offered that day. There is also a list of recent promos that are still available through MacUpdate.
Scrolling to the bottom of the page and clicking the "next" button I see that
DEVONagent is still available at a 20% discount ($39.95 vs. $49.95).
