You're missing a trick there TV, all of my cars end in 99 and not 95. The reason being if you sell 250 cars a year that £4 per car is a grand a year you're just giving away for no reason, over 10 years that's £10,000!!
The thing that always makes me laugh is when people pay in cash and the balance is £5999, they'll give me £6,000 in notes and when I've finished counting I'll reach for my back pocket and they always say "oh no don't worry about the change" so I get an extra £1. The thing is if they went to the Co-op next door and spent £9 and paid with a £10 note and didn't get their £1 change they would soon start complaining, so suddenly that £1 is important to them!!
Now if my figures ended in 5 instead of 9 they would probably be much more likely to want their £5 change, and I'd miss out on my free £1's lol.
