best price i have seen while i am searching in the interner :))

Had a great price on the parts that I wanted, informed me immediately that the products were back ordered from the manufacturer, and wanted to know if I wanted the parts dropped shipped from the manufacturer or what. They said if I wanted to wait it would take around 2 weeks to ship, they arrived in a week.
