I don't think printing it would make a difference. I handed a printed copy to the cashier when I used it Saturday evening. He scanned it but the discount did not apply until he found a large checkbox with the offer under my account. I'm guessing it is now gone for everyone
So has anybody actually tried it today, or nah? I have it printed out, but that post-work laziness has set in and I don't feel like driving a mile down the road to see if it works.
