The wing mirror glass was described as RH or LH. This made it hard reserving as I wasn't sure what was OS or NS. The photo for the LF looked like my glass on the OS. So I ended up reserving the wrong side. Because I had reserved the wrong side, the cashier wanted me to pay full price for the other side as my 35% discount only applied to the side I resverved. I found him a bit rude, he did give me it on trade price only after I said I would reserve an order for the other side and wait. "Well that can take at least another half hour or so" he said. I don't think he wanted me hanging about, so I got it on trade at just a quid more than my original reservation. He made me feel like it was my fault for the mistake though. The photo was wrong and the description was confusing.
