There may not be alot intentionally hiding sales or shaving hits, but every sponsor gets sales from returning typeins after the cookies have expired or from new computers, errors in tours, hosted galleries, 404 pages, etc... I've done work for some programs that generate a decent amount of non-affiliate sales even though they don't do any of their own promotion and rely 100% on affiliates. It takes a hell of a lot of QA to ensure that 100% of affiliate sales are credited properly, and even then you'll lose a lot of surfers once they go home and typein the domain from a new computer.
