apply coupon discount

Dear all,

My store have price break or wholesale setup.

For example:

1 - $10

5+ $ 8

10+ $6



Let say I have promotion to offer $1 off on a selected item. Now, it seems to apply to all level of price break. Is it possible to prevent customers from getting $5 ($6-$1) when they purchase 10 pieces or more.



Please advice. Thanks!
