I feel really bad seeing this, because I just bought him for $114.99, but the nearest Costco is 42 miles away, so let me do the math...
Assumptions:
1) It would not take multiple trips to find him.
2) It'd require long detours to get anything else of value out of the trip.
3) Gas prices won't change between now and then.
4) We'll disregard environmental implications of everyone driving around individually.
First, have to add sales tax to the figure, if I weren't buying him online. State sales tax is 2.9%, but where the Costco is it's apparently over 3.75%. So, $2.9996 on a $79.99 purchase, so that brings Metroplex to $82.9896, or $83.
The Costco is 42.6 miles away, so we'll say 85.2 miles of driving round trip. The way my wife drives I-25, that'd take just over an hour, but our car has aged poorly and the wind wouldn't be at our backs either way, so our gas mileage would probably be a lousy 22 miles per gallon. So, we'll say 3.87 gallons of gas. Gas prices are around $3.55 for 87 octane gas here. 3.87 gallons at $3.55/gal would cost me $13.74. So that brings Metroplex to $96.74 for me.
So I'm shorted $18.25. Hilariously, that's right on what I'm supposedly paid per hour at my job, so the difference between ordering him online and driving one hour to Costco is approximately equal to one hour of my life.
For those who want to quickly run through that for themselves, but prefer algebra over word problems:
a = Cost of Toy at Store
b = Sales Tax at Store's location (% of $1; This can be found through
a site like this)
c = Cost of Gas ($$/1gal; This can be found through
a site like this)
d = Distance to Store (miles)
e = Mileage of your Car (miles/gal)
Final Cost = a + (ab/100) + 2(cd/e)
[Now watch me have made some
really embarrassing mistake writing that down.]
You know what'd be cool? To have a calculator in the Toy Sightings section that would reference sites that provide gas prices and tax rates at stores, and let you plug in your location, gas mileage, and such, to quickly calculate and compare shopping at different stores.
