Well, I wouldn't call it fudging numbers at all. I'm telling it exactly like it is: I got the $1.20 one-off discount, was able to sell a few items for $5, so I got 3 games for about $6. The problem with your hypothesis is that the reality is that I probably won't be able to sell off what I've got left because they're the bundle dregs. It's not me being lazy, per se, although I will argue that I'm not the kind of person who's likely to repost something over and over until it goes away. If I don't get any takers after 2-3 posts, that's usually my limit, in part because I know that interest in bundle games waxes and wanes; you get diminishing returns for your posts five days and eight days and two weeks after a bundle goes live because people who are trolling the cesspool for that thing you're trying to get rid of have a) given up or b) gotten one from someone else already.
So it still boils down to whether you're okay with paying a premium for whatever the headliner of the month is, because, yeah, you may get 1-2 items in the bundle that you would actually like, but, once again, these will be rebundled--it's a matter of when not if. So you can get Deponia Doomsday in a monthly now or wait three months for it to be in a weekly, maybe with a bunch of other stuff that actually makes you want to buy that bundle (and that you know the identity of in advance because weeklies <> IR mystery bundles).
So buying Humbles is somehow funding the federal government? How does that work again?
