UR Magazine Coupons - don't bother

I went to a store with a coupon featured in Rogers' UR Magazine. According to the hype it would give me 50% off the actual Price of the item I wanted to buy. I grabbed the item and presented the coupon. The store personnel told me that they could not honor the coupon because it was unknown to them (the coupon had their logo and coupon code). Then I waited for them to clarify the problem and they told me that the item was already on sale by 30% off. I pointed to the fact that the coupon said that the 50% would be reduced from the actual sales price. They argued that they could not give me a 30% and then a 50% because it was against their policy. Then I inquired why would they include a coupon for that item in the magazine and not honor it. They told me to go talk to Rogers because it was their doing. So, I went to the Rogers store and the sales clerk said that they were not responsible for their coupons and he couldn't answer any of my questions. SO, right now I am a little bit more than pissed because their customer service doesn't know anything, their sales partners / affiliates don't know s**t and don't honor their own coupons.
...On top of that...
One of the sales guys at the store I presented the coupon to said that I could have "reproduced" the coupon, because it was not known to them. I kind of stared at him
(I was trying to figure out why the hell would anybody go through the process of recreating a "fake" coupon with official logos and official scan code and then present it at a store to risk being put in jail). Then one of the other sales guys said that it could not have been "made" because it had their code and it seemed like it had been ripped out of a magazine... (DUH!! really? that's what I said 30 minutes ago)

My final verdict on this:

That store just lost me as a customer, I will never buy there again. As for Rogers (screw the iPhone, they are the only ones able to offer it in Canada) as soon as my contract is done I am going to another company. I never had this problem with Telus, Mike or Bell Mobility. (by the way Fido is also a company of Rogers wireless)
