No one asked you to reduce your price.
It's your right to mark the price on your own item. I know for a fact they were just trying to assist you in selling your rim by suggesting a more reasonable price as many sets have sold for around your asking price for a single rim.
Again, I'm sure people will see that there has been rim sets sold for under 1,000 and just rather wait until another comes up.
I hope you're not offended by their assistance. I posted the link to the rim set that I bought because I was fortunate to find this set to replace all 4 of my curb rashed rims.
Best of luck with your sale!
