That's not what I got from the OP's statement.He simply expected to pay for a reasonable priced repair.He did not expect a free repair but he thought the ammount was excessive and I agree with him.
That's the way I read it too. He states in the OP that Leica wanted $852 to replace the two objective lens. That is excessive by any standard, grey market or not. That's more than I paid for my brand new pair of swarovski 10x42 slc's about 12 years ago.
If he'd come on here complaining that they wanted $200 I'd say suck it up and quit whining. $852, on the other hand, is unethical price gouging.
