Personally, I think you would have had to have a lobotomy to spend 500 quid on that (even 300). There are loads of lovely scents there but many for me would be in the 'wrong' form- ie I would prefer nectarine cologne rather than bodywash. For that reason, I would no buy it for myself but would definitely not mind if anyone wanted to buy one for me as a gift!
I think the extravagance point is by the by. As others have said, many people spend £300 a year on takeaway coffees. If you are concerned, maybe have a deal with yourself that you will try to save £300 from your normal expenses next year.
