Kheper Games's e-commerce site is wildpartygames.com.
From the publisher's web site:
Kheper Games, Inc. was founded (as Kheper Publishing) in 1995 by Brian L. Pellham. Kheper Publishing became Kheper Games in 2001 when the company moved from just publishing game books to offering a wide variety of adult games and novelties.
Kheper Games' office and warehouse are based in Seattle, WA. We have a presence at most major gift shows, party shows, and adult expos. We have sales representatives at New York and California gift shows, and most distributors in the adult and romance marketplace carry our products.
Kheper Games reached a major milestone in October 2003 when we sold our 1,000,000th game. Half of these sales were in 2003, due to increased momentum and the exciting new products we have released in the past year.
