I've always wondered if they actually make any money off gift cardsNo., it is just good business by the Cashrewards Team.
Last week they must have been making a killing as all the Amexers were pushing through large orders buying many months of GC spend in order to be the 50% Transfer Reduction.
So when people are throwing $$$$ at you there is need to have a special offer.
Whereas this week their Amex based customers would have dropped off the face of the earth, and so they have an offer to entice the non-Amexers.
