Idine does have a way of knowing. It depends on whether the restuarant at which you ate reports it or not.

I have usually gotten points that were used in conjunction with discount coupons. However, one time, I called to inquire why my points have not posted, and the Idine rep. informed me that it was due to the fact that I used a coupon.

In summary, in most cases, you will get points even if you used coupons. However, there are restuarants who make note of it, so you won't get to "double dip," so to speak.

Bottom line is, don't ask the Idine representatives whehter or not you could apply discount coupons and earn points. They will ALWAYS reply, "No."
