As the book had already been stamped by Coutts- Mercier with the CIT logo they proposed that the book be given at a reduced price of £10.00 (sterling). This proposal was accepted by CIT. Coutts Mercier therefore sent a credit note out for the full price and a new invoice for the book at the reduced price. _lc _md204
