I had a bad transaction with zzp less than a month ago, so I posted in General on CGP and Zoomer was first to reply saying he was out of town, but would get to the bottom of it. Turns out that the valve springs I ordered were out of stock. They offered me a used set and $20 back.... That same day they came in and my order shipped within 24 hours.
I never used to be like this, but if you order from ZZP and it says its in stock, its probably not. Expect to wait a few weeks for anything you order from them.
