Daz has only bought all the items he had in his Rosity store and from what I know they will be released from time to time to the PC Club or maybe to the Premium Store as well. As DAZ broker you can still sell anywhere else, just not the products you have up there because DAZ is exclusive only. They don't have contracts that forbid brokering at other sites.
