Many thanks to you all - it reassures me that I'm not completely out of line with you! I think the cost price is a good idea when it's a cheaper vase but when it's a big expensive one I think you might have to spread it a bit over time. I suppose it depends whether you've been specifically asked to get it in for a customer, whether they're rich or not and whether or not you like them!!? Obviously, if something's broken that's different...
