I purchased a bunch of brake parts, and ended up selling the vehicle without the brake work being done. I went to return the parts (which required me to post them to 3 different warehouses at my cost) understanding that I would be charged a 20% restocking fee. When I got the credit, I calculated the percentage they kept and it added up to PRECICELY 30%. I cried fowl to them and they said I had not returned all parts (... a lie) and that was the reason they kept 30%. Bull**it. They tried to scam me, I caught them.
