The EBAY manual is an original printing, yours is a re-print of the same thing. Reprints have a slightly different cover and are generally thicker than "first editions". They contain exactly the same information so I have assumed that the paper stock of the reprints is thicker. It seems to be when you have them side by side.
Christo is right. Shipping is getting expensive, isn't it Tom?
To UPS a set of rotors and pads ground is around 20 to 25 bucks. Make it a 2nd day and it jumps to around 75 :ugh: .That,BTW, is a "hard cost" there is no "handling" fluff in there.
