I bet they have no problem collecting on time. Last few months have been crazy w/ CJ's payments... I'm generally not one for conspiracy theories but it looks like they are either reaping the benefits of a few extra days' interest or are having trouble meeting payout demand.
Lately I've moved whatever I could away from CJ to smaller networks. Better conversions, better cpas, better offers, and AMEN for weekly wires, especially when CJ can't even handle once a month any more.
