Well I tried my hand at Kroger today:
Total out the door was 20.13 with a 48% savings of 16.81. I think the average cost was about 1.05 per item. i would liked to have gotten more because there were several things I would have liked to picked up on the cartbuster sale but i didn't have the coupons I needed, bummer.
Then again I did get to write a lot of the pricing on stuff to compare with the pricing elsewhere. All in all it was a good when combined with the Wags trip(posted in the Wags forum) Spent a total of 72.26 and saved 54.10. I think I am hooked!
