FYI - P3 in Memphis is showing 30% to 50% increases on some new Piper parts, although the May 2008 price lists does not. I will check June's price list and confirm.
Follow-up - P3 is using June 2008 pricing. Some items have increased quite a bit. On the other hand, Des Moines still shows May 2008 pricing on the same items. Might be worth your time to shop around until June 1.
