The good people at Amazon have the very best online shop (IMHO). Good service, good selection, easy discovery and very nice Encyclopediability (i.e. the property that you always learn something new when using their site by scanning the entry next to the one you were looking for - as when reading a paper encyclopedia). But even the best make mistakes. My latest receipt contains the following staggering numbers

-------------------------------------------------------------------------
Ordered Title Price Dispatched Subtotal
-------------------------------------------------------------------------
1 Speech and Language Processing 43.74 GBP 1 43.74 GBP

1 The Mythical Man-month 28.74 GBP 1 28.74 GBP

1 Applied Cryptography 47.29 GBP 1 47.29 GBP

1 How to Solve It 39.38 GBP 1 39.38 GBP

-------------------------------------------------------------------
Subtotal Including VAT: 159.15 GBP
Delivery Charges Including VAT: 8.64 GBP
Total Including VAT: 3,286,790.31 GBP
VAT 25.00 GBP%: 33.57 GBP

The VAT comes in a only 0.001% (not the 25% mentioned) so the taxes are nothing to speak of - but the handling fee of 3286622.52 seems excessive.
