Here's an interesting price comparison done by the folks at a neat site: improbable .com.
With gasoline in most of the world at record-high levels they figured out the per-gallon cost of some everyday household items. It ranges from the lowly Coke ($3.58 per gallon) to mid range items like Windex ($19.64) and Hidden Valley Ranch Dressing ($30.00). The grand-daddy of the comparison was White-Out at $400.46 !
At some point I will put my shaky math skills to work and calculate the per litre costs. In the meantime, I'm going searching for a bubblin' crude of White-Out !
