Good for you, KGZotU. Sounds like you've got a good set up for stashing away some money since your rent is so low, except for the fact that it is sooo expensive to eat up north. I spent a couple of months living in Iqaluit a number of years ago - early 1990, I think? Back then, I remember that a bag of milk was $12, and a case of coke (24 cans) was $24. The farm box you mentioned sounds like a good deal though, if it means you'll actually get decent quality fresh veg regularly!
I'll be with you in spirit this month, as I'm aiming for as much of a no-spend month as I can manage. I do have some recurring expenses that are not very mustachian (for example, a dog walker once a week for my late days at work, and a car!) but outside of those, I just have no money to spare this month due to needing to take my car in for service and renew my license. I'm even hoping, having spent just over $10 on milk and produce, not to have to go back to the grocery store before my next paycheck on the 25th. There is lots of stuff in my pantry and fridge/freezer, so I think I can make it ...
Good luck!
