Doesn't make sense. If only one game you want is in the bundle, then it's worth the 5-6 dollars you'll pay since you would have to pay close to same amount elsewhere. You'll get the soundtracks as well, and the games are free of DRM. Last bundle had shank 2, and even though I already had the game, I would have paid the 6 dollars JUST for that soundtrack. Considering that most commercially available game soundtracks go for around $9.99 on amazon, you're getting a good deal.
Plus, you get extra steam keys for repeat games; I usually just give those to my family members, so nothing really goes to waste. You're also looking at one game for $3 vs 8 or so games for $7. You spend way more with the one game a week.
