Rainbow Foods Double Coupons

Rainbow Foods is running a special coupon promotion this week. On Wed. 1/27 you can double 10 coupons with at $25 order instead of the usual 5! I am hearing that some Rainbow Foods are really checking the coupons at the check out to see if they say "Do Not Double or Triple." If they say this, then they won't double them. I have not had this happen to me at the EP Rainbow, but a friend of mine did. We'll see if this is something that they start to implement consistently or if it's like other things that seem to just go away.
