Not the case here. I sent payment the very next day. Seller acknowledged he received it. Promised it would ship on certain date. It never did. He gave me another ship date. Still never got shipped. Finally he quit responding to emails. I posted this in the scammer section and he shipped it THAT day. (Tracking number verfies this). It took him over 15 days to get it to the post office. This was certainly not the post office's fault.
I am 100% confident that I would have never received my parts if it wasn't for posting this topic, and the topic on Yellow Bullet.
If you are too busy to ship the stuff, you shouldn't list it for sale on the internet. If you have read any of this guy's responses, you can see that he is rude, verbally abusive, and an all around jerk. He should be banned from selling on here.
