W211 Discs and Pads - bargain

I've just replaced the above. Got Febi Bilstein Blueprint discs from a seller on A---, you know who, for £30.84 including delivery. I was a bit skeptical because they were described as Febi Bilston, so wondered if they were knock offs with a similar name, but they duly arrived dispatched directly from Febi, themselves.
I also ordered pads from the same seller for 20 odd quid, but this time the order got cancelled with the explanation that although the computer shows stock of 5 sets, they can't be found in the warehouse, so bought Meyle pads from KMS for just under £30.
Only downside, I bought 2 wear sensors elsewhere, not for one minute thinking that, in their wisdom, Mercedes would have different connectors for left and right - Doh!
