Think of CBS as your marketing/sales force and your purchasing department. CBS brings you new business through the barter system and we earn our commissions through transaction fees. No transaction fees are due unless we find you business or fulfill your trade requests in spending your barter dollars. Your monthly membership fee includes the promotion of your company to other CBS members and our reciprocal partners, both national and international. We also send twice a week Barter Blasts with new trading opportunities, sponsor exchange events and publish new trade availabilities on www.cbsbarter.com on a regular basis. See Reasons To Join if you doubt that we don't earn our fees.
