Discound Coupon not for Price Group customers

[crystaldreams]

Hi! I looked into it and I didn't find any other similar thread.
I am using the latest 1.5.5e version for my shop and I am thinking on making Coupon codes to share on my FB and all my social media in order to encourage new customers, or returning customers, to make more purchases.
The problem is that I have three discount group pricing customers as well whose already have 5%,10% or 15% off because they are really good customers but I can't offer the coupon to the too because the discount will be too high, my intenction is not to enable them to use it or let them choose if they prefere the coupon code or the Price group discount.
Any suggestions on how to solve that?
