Being a starving student, I've learned a few tricks of the trade when it comes to grocery shopping.
1. Buy the dollar wheat bread: what you lose in nutrition, you gain in sheer number of slices!
2. Buying certain foods in bulk: cereal (Malt O Meal cheerio knock-offs!), peanut butter, giant blocks of pepperjack. The uglier the package, the more you save.
3. Oreos cannot be cheapened. If you can't afford name brand, you don't buy the cookies.
4. When the store has a ten for ten dollars sale on anything you're likely to eat, stock up! You will be thankful for the 15 boxes of brownie mix someday.
5. A $1 bag of house-brand pretzels can be a lifesaver, providing "lunch" for days on end.
The reason I bring all of this up is that the other day I rode my bike to the store in an effort to be green and thrifty and also because it was a nice day out. I ran into a few issues with this trip, though. The issue of milk (not to be confused with the issue of blood) was easily remedied: buy a half gallon, so it will fit in the pannier more easily. The issue of bread was more perplexing. If I bought my usual dollarloaf, it would surely be wadded into a big doughy ball by the time I got it home, smashed in with all the other groceries. But I was out of bread! Whatever to do?
Enter my good friends, the tortillas. Yes, slightly more expensive. Yes, will make fewer sandwiches. Their one redeeming quality (besides being tasty!) is that they are infinitely flatter than a traditional loaf. Satisfied with my wisdom, I placed the bag into my basket and strode off in search of a huge tub of raisins.
