The co-promotion scenario is an interesting one - while the business benefits from having this charitable association during a sale (especially at this time of year), I guess the charity in question must also benefit in some way from the promotion to a wider marketplace by the association with the business (putting aside whether the charity is worthy or not of course). Charity organisations must be in an incredible amount of competition around Christmas. The cut-open teddy story was horrendous - Is there a charity watchdog for reporting that sort of thing?
