What if Andrew offered you MSRP of $99 but $15 shipping?

The AA pulley apparently has a steel plate at the end that increases the weight, but probably makes it more rigid (not that BMW or K&N have a problem with plastic there). The extra weight may affect shipping charges, but an extra pound is not going to be measurable on the racetrack where some members seem to drive all of the time.
