The 50% discount is a smart move on their part -- taking advantage of this massive increase in security awareness to grow their marketshare.
Their product is superb. As mentioned... they are not affected because all encryption is done locally on your own machine... with a key that you control locally, and is never shared with them or anyone.
Most password vault programs encourage the behavior of using unique passwords for ever single site. For all of us who follow this advice... we are at MUCH lower risk right now because any exploits are limited to the single site of any breach. For most others who use a single password anywhere... a breach at any single site (say for example a single store)... make them additionally vulnerable at their bank, their IRA, their stocks... etc. Very scary.
I believe that 1Password is at the top of the pack of such programs. Others work... but I think that 1Password is simply the best.
