The UltraEdit bundle deal is back on the BDJ schedule (for Sept 14 - Sept 18). As wraith808 said, the deal boils down to getting UltraCompare and UltraSentry for free. Like mouser, I prefer Beyond Compare, but UltraCompare is definitely a worthy compare utility. I have found little use for programs like UltraSentry. But others may have different opinions.
If you're thinking about getting UE, it's probably a good idea to wait a couple weeks to get a couple other programs thrown in for free. But I guess I'm stating the obvious.
And don't forget, if you'd prefer UltraEdit Studio, the IDM sale is still on (something like 40% off) and it apparently applies to upgrades, too.
