Who are these traders who offer two prices? Is it common? Never happened to me; it would be daft to announce that you were planning to cheat the revenue and involve the customer in that deal.Why embarrass him ? You don't know who he is, for a start. You never know. He might be a fine upstanding bloke who will grass you up if the deal looks dodgy or if he buys and has a complaint later. Better to say that £1,300 cash for a quick sale is your best price and leave it at that. That leaves the customer to speculate, if he's so minded, but doesn't tell him that it'll be £200 more if you put it through the books.
And then it does leave the customer to think that what you do about the cash is a matter for you, if he bothers to think about it at all.
