Who is following anyone's legal advice?
I have been involved in several consumer fraud type cases. It sounds harsh, but it is basically a situation in which the consumer feels that they have not been treated fairly by a business. You try to reason with the business, and when they do not respond to your satisfaction, you get a lawyer, or file in small claims court, or write to your Attorney General, all of which I have done and have worked out favorably.
It's really not about what Target meant to do, it's about how they advertised a coupon and the parameters of the future purchase.
As far as requiring 'management intervention', imo, and I am not a lawyer, it is the terms of the ad which are at fault and up for dispute, not how the coupon was ultimately handled at the point of sale.
I knew from the beginning that someone was going to get this deal one way or another, but I never thought it would be handled so inconsistently on so many occasions. That alone reinforces the 'bad ad' claim. If it was a properly worded ad there wouldn't be so many interpretations.
