return. i heard of one. her power chord was
broken. she went to the store, bought a similar model.
went home, exchanged the chord. went back to store.
kpkb that the power chord was broken (actually hers) and then do a
return. now, how sneaky can that get?
That remins me of something I did as a juvenile, maybe 12 yrs
old. Me and some friends needed to purchase a baseball at
Woolworths. There were 2 types available; the expensive one and the
cheaper one.The price was on the box. Of course we had to examine
them both to see what the difference was and we 'accidentally' put
them in the wrong box when finished then purchased the 'cheaper'
one. 
I still lose sleep over that.
