I did look on eBay, and the prices looked similar unless I was miss reading it and the 500 quid price was for 4 alloys but it did not seem to say that when I looked.
Not saying I am right , and there are reps that are good and there are reps likely to crack ( been there got the t-shirt)
Edit .... you are right the similar price was for a set of 4 , so my appologies
