I have been buyign polishing and abrasve supplies from moleroda for years. Yes, their shop works etc, but it is their knowledge and customer service that sets them apart form others.
I am so glad I don't use seller central any more. I persevered for 2 years during which time amazon seller central never ceased to annoy me. How they make amazon so easy to use as a consumer, but so difficult as a seller is beyond me.
