Been going there for years returning the same aluminum rollers and getting top dollar. I save up for 6-12 months in between each visit. Last time I went they gave me the lowest price and said it was because of the coating. Here's what happened - he asked me if I had ever been there before and I told him yes many times but not for a few months and I told the guy I usually get top dollar. He went and asked somebody, came back, weighed it, dumped it in a bin and gave me the receipt for the cashier. That's when I found out I got the lowest price. He could have said something before dumping it. I will go elsewhere and see if I get the same treatment. My brother in law had the same type of thing happen to him a while back also so it makes me suspect they try to rip people off.
