The $400 wheel locks "that'll only cost you $15 extra per month, think about it, you don't want your wheels stolen, do you?" Let's see $15 x 60 = $900. Damn, $900 for wheel locks that were priced at $383! That's like 2.5x the original cost. No, these are really $40 wheel locks disguised as $383 ones.
This is an example of back-end rape.
