www.greekloft.com had posted on GC but was pulled because they were soliciting. But I ordered 3 Greek sorority calendars to give to undergraduate officers. They did have cute AGD and Squirrel cards but I didn't want to pay $15 for 14 cards plus any shipping or handling.
I just looked at their site again..only a few sororities, not all 26 NPCs. Maybe they are a small company and will add fraternities as they grow.
