As a college student, my shopping routine and budget follows as such:
Walmart / Sam's Club
Frequency: Once every two months
Expense: Around $250 per person (I live with one roommate)
Contents:
$10 - Various greens and fruits (this serves as the most inevitable reasoning for all the horrible foods I am about to throw in the basket that follow).
$40 - Frozen section; pizzas, Boston Market dinners, five lb. bags of buffalo wings, etc...
$15 - Chips (and if we're feeling classy, dip will follow - $5 variable differential)
$40 - Steak, ground beef, other manly / awesome things that put the grill to good use.
$40 - Beer (how cliché)
$40 - Liquor (most likely Jagermeister)
$15 - Coke, Pepsi, Red Bull (for the Jager, of course), etc...
Remainder is typically used within the depths of the five dollar dvd bins, deodorant, toy section (if we end up going at 3 am on a Tuesday because there's simply nothing better to do), etc.
One week later - All aforementioned items have been consumed (possibly even the dvd's).
Following seven weeks - Every meal is provided via take-out (typically chinese, taco bell, Qdoba, Su
ay, etc.. These are all within 500 yards of my apt.)
The next week (eight weeks from the last visit) - We return to Walmart to be responsible adults. The process repeats itself as nature intends.
