Lets do some calculation, shall we:
US Federal minimum wage: $6.55/hr (it goes up to $7.25 in 2009).
Current price of gasoline: $1.78/gal (I filled up today, it is much cheaper than in September!).
Mileage for my big gas hungry SUV 16 Mi/gal (It has a nice built in calculator!)
Distance to my local WalMart: 7.1 miles (Yahoo Yellow pages!)
Distance to my nice friendly Apple Store 3.4 miles (Yahoo yellow pages again!)
Additional miles to WalMart: 3.7 miles (.23125 Gal, $.42 [rounded!])
Now let's get there at a reasonable speed: 30mph, takes 6.8 minutes, another $.74 at minimum wage.
Now we're left with $.84, or in minimum wage terms, or about 7.7 minutes to argue with the minimum wage clerk (I'm being kind here!) at the WalMart desk.
That is to JUST BREAK EVEN.
Not included:
Even more arguing with the clerk about finding the thing.
Time to park (maybe a wash, I don't know).
Attempting to get past all the customers who don't know what they want (what is a gigabyte?).
The pain and aggravation of having to go to WalMart in the first place.
The fact that my time is worth more than minimum wage (most of the time, I am unemployed right now, but the $900 in unemployment every two weeks is something!)
And last but not least: I just don't like WalMart. They (mostly) sell cheap junk!
Enough said!!
