The good news: against expectations (well, mine anyway) the MacUpdate Promo bundle has sold well enough to unlock the final application in the ten-pack, the Aquafadas slideshow creator PulpMotion. You now have until shortly after midnight ET to get the full bundle for $49.99; see my earlier post for the full app list.
The bad news: right now it appears that http://mupromo.com is responding only intermittently, perhaps due to heavy volume. If you can't get to the site immediately, wait a few minutes and try again.
Update: The original deadline appears to have applied only to unlocking the full bundle; you now have another eight days to buy, if you choose.
