The Costco cash card is part of our program - we're one of the kiosks on the way out of the warehouse. Members get approximately 8-10% of the purchase back in form of the cash card (which I fund). If a customer comes to me via Costco, I guarantee they're going to get at least 15% better deal than through our regular business. Costco is a $105B entity. When they say jump, I ask how high! They also send us $$M in biz every year. Demanding but fantastic partners.
