Maybe I have been living under a rock but I just found eMeals.com and I'm pretty impressed! Emeals.com plans your menu for you around meals you love (including gluten free) then, they also supply the grocery list oh and it gets better...they use the sales at the grocery store to help you save money!
I think it's probably better to use our matchups and print the coupons too but overall, having a menu for me that also comes with a grocery list is flat out amazing.
If you want to try it out, you can get one week FREE! (The plans are as low as $5 per month).
Let me know what you think!
