Mike is right. This is what my conversations are usually like:
Will: Hello?
me: Hi Will, I need a headlamp switch and a starter motor.
Will: Yeah, I got those. $75 for the switch and $90 for the starter.
me: I'll take both. Remind me of your PayPal address again?
Will: willtillery at roverguy dot com.
me: Thanks, I'm sending payment now.
Will: Okay.
me: Catch you next time.
Entire transaction takes less than two minutes, parts show up in a surprisingly short time. Parts work, truck works, I'm happy. In years of buying stuff from Will, PT, Paul Grant, and Marty I've never been hosed. Once I bought a headlamp from one of them, it arrived in pieces (broke during shipping), and I got a replacement in a jiffy. These guys do it right. It may seem weird buying a part from a guy you've never heard of on the recommendation of a couple strangers on the innernets, but these vendors have spent years establishing trust in this community.
