What I know: Just4U program is officially being launched this Wed, 6/27 in Northern California. The program is being launched systematically in different regions with a goal of the program eventually being nationwide. I can confirm that I was already able to sign up with my Nor Cal address and my Free Egg eCoupon worked. I purchased eggs and the total cost showed as $0.00.
The change over in the registers (those which WILL and those which WILL NOT accept both an eCoupon and a paper coupon) is correlated with stores preparing for the Just4U program. Seems like once you get Just4U, the stacking is over and until then, you may continue to stack.
I’ve got a list of my own questions, but what do you want to know from Safeway regarding their coupon policy? Leave a comment and let me know before the end of the day!
