So have all the Mac software bundle sites just folded into one?

It seems as though all the sites that used to be individual have been slowly becoming each other… the latest appears to be TwoDollar Tuesday, which is promoting exactly the same bundle being promoted (and sold under their own name) by:

Stacksocial
Hongkiat
Mactrast
CultofMac
iLounge
9to5Mac
Thenextweb
BGR Deals
MacAppDeals
And who knows what else.

Extra amusement: TDT and a few others are promoting it as “exclusive” - methinks they don’t know the meaning of that word, clearly.
So what’s up? Is Stacksocial itself just cloning itself under different names, or…?
