I have a friend that does that with expensive
Canon DSLR bodies. He bought the original 10D
there. Then when the 20D came out, he took the
well worn 10D there, and got 100 bucks back and
the 20D. Couple weeks ago did the same thing when
the 30D came out. Got a couple hundred clams and
a brand new camera. Needless to say I smashed
out his car windows and stole the F**kin thing
so that I wouldn't have to here about his heroic
feats at Costco ever again. Rotten SOB.
