I'm just curious if you did file a lawsuit, what you think you'd be entitled to? It seems to me that your compensatory damages would amount to $50 (your "lost cost" of not being able to use the coupon). Punitive damages wouldn't apply as BB did not put this coupon out with the direct intent of harming you in any way. We all know what consumers really get post class-action lawsuit due to the lawyer fees...
Think about mosquitoes on a elephant. Does it bother the elephant? You have to ask the elephant. Do the mosquitoes get some blood? You'll have to ask.
Small claims court and 50 per coupon you printed not copied.
Possible treble damages if you can convince. =s 150 YMWV.
Or add in some discrimination. Some got it and I didn't.
