Remy European Hair Extensions on Ebay?

I'm just about to pay 200 pounds for Hollywoodglamour Remy European Clip Hair Extensions through a salon but I have just had a look on Ebay and there are loads on there for a quarter of the price which also say they are Remy European hair. I'm guessing this is a scam cos of the price difference but I just wondered if anyone knows if it is definately worth paying 200 or if it is perfectly possible to get just as good qaulity for much cheaper....?
