Couple of points, first,
35 grand is taking the piss!
Be careful with that website,
these chairs for example are copies. Copies never last and are not as comfy. And, in the UK, illegal to sell.
I have two Eames chairs, although only one in use, and they are glorious things to sit in! The official European ones are made only by Vitra , it's Herman Miller for the states and there are tiny differences, in particular with the base, but in practice it's no different.
If your set on a HM, MOMA in New York do it to members (£110) for £6336 plus £460 shipping to UK. £7500 is a good price!

In the UK, Utility are good, I bought mine from them, and often have 15% off sales. Outside the sales, pretty much every retailer will charge RRP, currently circa £8900.
They are not indestructible, so if you do buy an older chair
this company in Germany are good for spares.
Oh, and if you do get one, will will soon fall into the rabbit hole of mid century furniture, and it's a wonderful but pricey place!
