My wife was at wal-mart yesterday, purchasing a can of Scotch-Guard. She noticed that one of the cans on the shelf had a coupon on it (buy this can of Scotch-Guard, use this coupon to get $0.50/off at the register).
She picked up the can, inspected the coupon, and noticed that the coupon expired in 1999. She also noticed this can "looked" older than the other cans on the shelf (different design, looked more dated).
So ... what do you
think happened to this can of scotch guard? Why do you think it's still there at wal-mart after all these years? Where did it come from, and why does it pre-exist that store's opening?
All theories welcomed :) I can think of a few but would like to see what everyone else comes up with...
A couple things to note:
a) A coupon that expired in 1999 was probably made in 1998 or 1997. I recently bought a can of pickles that had a coupon that expired 2 years later (and thought that I wouldn't have wanted to buy the same can of pickles after it had been sitting on the shelves for 2 years). It's probably safe to assume the can was made around Jan 1998.
b) Wal-mart has an inventory turnover of ~8.4, which means items on weighted-price-average sit on their shelves for ~44 days. This item has been around for 4602 days (assuming 1/1/98 manufacture).
c) The wal-mart store (777 story road, store #5435) first opened 8/25/2004. (quick google search turned this up, makes it easy to find opening dates for wal-marts!)
Note that I did find store #2524, 5502 Monterey Rd in San Jose, was opened 1/29/97.http://www.econ.umn.edu/~holmes/data/WalMart/store_openings.csv
