Just took a look at their new "Super 5" Promo.

Price for 5 games: $4.95.
Price for 4 games: $4.96.

Looks like a bug :)

Not a bug, it's to entice you into getting more games you may or may not get around to depending on your backlog. ;)

No bug, it was explained in the official topic about the bundle

It's hardly the first time it's happened. In fact, it's been the case with ever single sliding promo so far, and I doubt it'll change.

It is not a bug. ,_,

GOG works in mysterious ways...

Aside from what Garugo said, it's also sound math. 4 games is 75% off. 5 games is 80% off. 25*.08 = 5, 20*.075=5, +/- some change.

Hah, it's not a bug, it's a feature.

If only I could convince our testers at work more often of that truth...

Still, weird, already have VVVVV on steam so I wasn't interested in it.

It's a thing that happens. For example, GOG paid me upwards of $2 for allowing Master of Orion 3 onto my shelf.

Pfft. I wouldn't allow that turd onto my GOG shelf unless they paid me at least $1k. =P

25 x 0,2= 5
20 x 0,25= 5

I have to agree: it's definitely a bug. GOG owes excellent service to its customers and excellent service must include to make sure customers do not pay too much. In this case they should always automatically add the fifth game and never ever allow anyone to only buy 4 games. Hence a bug. But they are a bit lazy and probably won't fix that.
