Review (5/5): Cheaper substitution
I called Phillips Norelco's customer service (800-243-3050) and was informed that the reason for the price hike is more than likely due to the fact that the razor (HS 8420) is no longer being made and neither are the blades. He did state that the RQ 12 blades would work with this razor however which average ~$55.00 and are more readily available.
