So I fell off the wagon a bit yesterday...
The ending-real-soon Humble Bundle for Boom Comics had a few things that interested me (RoboCop, Steed and Peel, Irredeemable, a Cthulhu omnibus), so I took the plunge at the full $15 level - then did so two more times as add-on gifts for two friends. So there's $45, but only $15 on myself.
The bigger deal was that I've been building up a sizable amount of Viggle reward points. Their movie/TV store went away "temporarily" earlier this month, they seldom have any gift cards available, and the company's being acquired by another reward-oriented company. I've been wondering if the ebook store would go away soon, and yesterday I decided not to risk it. I cashed in about a month's worth of points for 18 books I had on my watch list. I've been estimating their ebook pricing at roughly 3000 points to the dollar, which would translate to cashing in about $137. That's a bit loose, though; I think their gift cards have a different exchange rate.
I'm not really bothered by dumping that many points, though. I still have over three million banked...
