We all hear the dealer catch phrases as to why they can't give you a better price for a certain item.
I thought it might be interesting to share the ones that you've heard...

I got these at the stamp show today:
Ooh-boy, you have a good eye... that's a real beauty!
I haven't updated my prices in that box since the seventies!
You wouldn't believe what these are going for now...
I don't usually bring that box with me - so the prices are not up-to-date!
