I started out my new budget with a pretty well stocked meat freezer, which made it really nice on the budget!!
My grocery budget is $25 a week. Each week I spend somewhere around that - I usually try to go less than that.
I keep track of how much I spent each week, and at the end of the month I total them up. I divide the total by the number of weeks I went shopping to get my average (as long as my average is $25 or less, I know I'm "on target" with my shopping and budget).
I then multiply $25 by the number of weeks I shopped. Then I subtract the total from what my entire budget was.
Shopped 4 weeks, and spent a total of $84.52
$100 ($25 x 4 weeks) - $84.52 = $15.48
The $15.48 (or what's left in my budget at the end of each month) goes into my imaginary "meat fund". As my meat supply starts to run low, I start watching sales for really really really good deals. I try to go for around $1.50/lb on ground beef, and less than $.75/lb on poultry. Then I stock up! Occasionally (and RARELY) I will "stock up" even if I'm not specifically running low, just because the deal is rare and extremely good (like turkey for $.59/lb?? - that's only going to happen now in the fall - once a year). I will make this turkey last several months :)
Usually I only find "good enough" sales on poultry (usually whole chickens). Hamburger is usually on "sale" for $1.99/lb - which is still to expensive for me, so I try and find big family sized packs that have been marked down for quick sale. The money I spend on the meat comes out of the meat fund, and doesn't effect my weekly shopping budget. Just today I started a list of my weekly shopping totals, and how much I have left at the end of the month to put towards meat. Then I also started a list of what goes into the meat fund, and what I spend out of the meat fund.
Things like hotdogs, bacon and sandwich meat do come out of the regular grocery fund. But I don't buy hotdogs or bacon very much, and try to get sandwich meat on sale.
Currently we are fully stocked with hamburger and poultry, and I have $3.99 left in the meat fund! I will need to be extra careful the next couple weeks here in October so that I can add to the meat fund. I try to be "extra" careful each week of course, but there are "drastic" measures that can be made sometimes - called "doing without". Ha ha.
It takes some planning and a little work, but it sure beats running out and having to pay full price for meat!
