I am always one that generally spends more than the set amount as I always find the perfect gift and even if too much I can't change my mind from it.

I would be peed off as well, especially when you have got such a great pressie. I personally find it better to have a max and min amount to give people a prompt as often people see 1 figure as a max amount. Would have been better to say $15 - $20 or something.

We had a group mothers group party this year for 4 year olds and we all had 1 person to buy for, and those of us with other children were to take a pressie for them. It worked well and everyone got a great pressie that was perfect for them!
