I will also clarify by explaining a bit of how I break down my budget. Some of it will seem strange.
His work lunches: This is something he takes care of unless there are leftovers available. He preference, his expense.
House money: We both pay "rent" into a joint house account that we are both on but I manage. This pays the mortgage, utilities, and if things are going well, repairs.
General expenses: Car insurance, medical bills, credit card, etc WERE being paid by the person that accrued them but he's not so good with paying stuff on time so I pay them and he reimburses me for his portion. This started after he hadn't paid his insurance for 6 months and forgot his credit card bill several times.
Animals: Dogs are a "luxury" that I won't give up. The keep us safe and provide the wonderful services of foot warming and room stinking.
I don't count initial start up costs for animals if it is a type of animal I intend to have for a LONG time. ie the goats. I'm going to have a goat pen for YEARS. I may throw a pig or two in there. I'm WAY to lazy to figure out the individual cost. I also just don't care that much.
Goats: The goats provide us with milk and antics. Our arrangement is that as long as I don't have more than 4 then they can fall into the category of semi-useful pets. Above that 1) we need more land and 2) they have to be more self supporting. And this is an average of 4. Babies that are intended for sale or freezer camp don't count. Goat food is supplemented by dehydrated free veggies, grocery store rejects and other random tidbits.
Chickens: First I need to yell at my chickens because they aren't laying right now. #$)SDHH@!& Chickens!! Chickens, similar to goat supplementation are fed via what the veggie guy saves or if he forgets, what I dumpster dive for them. Chickens are free and if they ever lay eggs again.. self replicating. Future hens to be sold and roos to be eaten.
Craigslist: That which happens on craigslist stays on craigslist. Seriously I have a CL jar in my desk. If I buy something off of CL the money comes out, if I sell something on CL the money goes in. It doesn't matter what area of the "budget" that item should fall under. I paid for the potatoes out of CL budget since I found them on CL. The exception to this is: If I am doing a major unload of stuff to save money for a specific thing I will pull those funds aside. Otherwise just general closet emptying goes in the CL mad money jar. It gives me a way to jump on crazy deals w/o feeling like I'm hurting another budget area. And money from selling some $5 and $10 stuff has a chance to build up and be useful.
Groceries: This is budgeted at $100 a month for food purchases at the grocery store or farmers market. During the summer I frequent the second's rack of our local FM where I can get HUGE zucchini for .25 and such. Again, these are grated, sliced, dehydrated, used in pickles, etc. I also try have at least one dish per meal be free items. Applesauce, traded meat, something.
I hope that explains a little more of how I do it. Everybody is different.
Edited to answer questions: I live in the Eastern Panhandle of WV. We are sandwiched between MD and VA. If you have a window with southern exposure you can grow something. It may be just a basil plant or some lettuce but it will eventually grow if the window isn't too drafty.
