Problem with KMart Coupon

OK so it appears there are issues with the Kmart coupon for $10 off your next purchase of $20....it seems that when trying to use it at Kmart folks are having problems with the manager telling them it has to be emailed to you and that it was only intended for NY stores...even though that was not printed on the coupon....Kmart is calling the coupon fraudulant even though it was on their website....I am not going to try to use it at Publix even though they would probably take it....Publix is so good about taking all kinds of competitors coupons that is it not worth the risk of using something that could be deemed fraudulant that could cause Publix to want to stop taking competitors coupons........sorry about posting it just to find out Kmart is not honoring it even though they say it is a misprint that it does not limit it to NY stores and that it had to come to you via email....whatever Kmart not a popular or good customer service move......
