We spend $25 a week on groceries, food, soaps, etc. But before anyone freaks out, I also live in Guatemala.
So, it´s a lot cheaper here and we eat very little meat, mostly just fresh veggies and fruits, plus pasta and rice (and beans, of course!). I´m rather worried that when we go back to Canada, it´s going to be SO expensive to get fruits and veggies. :S
