I spend about $40-50 a week, sometimes more if i'm buying a massive bag of rice, or a massive back of sugar (those i get about once every couple months).
So! I usually make a trip to produce section, where about 80% of my stuff comes from, anything from Artichokes to Zucchinis, all organic for me as well. Lentils I get EVERY week, they are a HUGe part of my diet, Vegan bread once a week or once every two weeks, my Vitamineral Green (which I get online), and just what ever sounds good. Luna bars are a must, and cereals, (I love the Kashi varieties) I keep a calculator, and make sure to include my tax, I currently have a dead end job till Uni starts, so I'm broke off my ass, which will only get worse, so my calculator is like GOLD to me.
I just love grocery shopping ^.^
Also, i live in Alaska, so my prices may or may not be higher then other areas of the country. But also, I buy for myself, since I live alone for now... and in the dorms, I really will not be feeding my roomies, so once again, my prices are for me only.
