I had a bad experience with Power Sports Super Store. Don't know if they are affiliated with Power Sport Parts. I suspect they are.
They sent me a scratched up led license plate holder, emailed them about the problem. Took 24 hours to get back to me, then wanted pictures. Sent pictures and then 24 hours later they asked for clearer pictures. The ones I sent clearly showed the damage. I sent more pictures with a threat of filing a complaint with Amazon and posting bad reviews on Amazon and posting forums. 24 hours later they sent a much nicer email and said they would send me a return label before the close of business that day. I could send them the damaged part and they would send me a replacement.
Four days later I sent email asking where is my label. They said sorry, they would send a new part right away instead and gave me the tracking number of my previous order. I could keep the damaged one.
Several days later I get the replacement. It was more damaged than the first one was. Now I have two useless parts.
I filed a complaint with Amazon and got an instant gift card for the total of the transaction.
I purchased the same item from a different vendor. It arrived perfectly fine with no problems.
As I said, I don't know if they are affiliated with Power Sport Parts, but they are both located in Texas.
I personally will never deal with either of them, just in case they are affiliated.
My two cents
