MMZ,
I too save more money on H&B than groceries. But I am also saving more on groceries now than I did last year. I've been tracking what I spent last year on groceries compared to this year and I am saving 20% more on average than last year. I have also discovered that I am getting freebies at the grocery store, something I never got before. So it all adds up in the end.
Good luck with the system and keep us posted of your progress.
