Dang! I missed being the one to unlock Pixelmator by just one or two purchases. (It was at $99,983 when I started the purchase process, and $100,025 when I got my purchase confirmation email. At $11.25-$12.25 to charity per purchase, I was that close.)
I bought it almost exclusively for Pixelmator and Snapz Pro X. The others might be interested, but I was close to buying Pixelmator on its own for $59 anyway, so when this was announced, I figured I had to. At 'worst', I saved $10, got $11.25 donated to charity, and got a bunch of other shareware apps 'free'. (Snapz Pro is the only other app on the list I've even considered paying for, but $69 for it was way more than I was willing to pay. I might also take to liking Cha-Ching, but I haven't gotten my serial number quite yet.)
