grocery game

I was talking to a friend about her grocery bill and this amazing website she uses to go shopping.  I am going to look into it, but after talking to her she was SHOCKED at MY grocery bill.  Last year, Ben and I started the cash system and for the most part it works.  I take my cash to the grocery store on the 1st and the 15th and if I go over my budget I don't purchase something.  

For instance this week I was craving cuties oranges, but they were $7 so, they were the last thing to go on the conveyor, when I hit my target I told the cashier I could not get them.  So, I told my friend my budget and she basically said, SHUT UP!  She spent almost twice that every week.  So, it got me talking with my husband and he wants me to start writing my ideas down.  Then, tonight my friend at church and I were talking and she too was like Shut up when I told her our budget. 

So, I tell you - every two weeks I go to the grocery store, on the 1st and the 15th, I take $150 with me for our family of 4 and that is our grocery shopping budget. What do you spend at the grocery store during the month?  Would you be interested if I started sharing weekly grocery shopping tips?  Would you share your ideas with me in case I do decide to finally write that book someday?

Disclaimer - I do not buy diapers or dog food on this budget - I go to Sam's for diapers, and formula when it was needed.
