Now they have an hour to find the gift. Firs the find a belt , but it is too expensive. It cost $30. Then they find a baseball cap . It is cheap. It only cost $10. But Daniel doesn't like this one. The one Daniel likes is $25, they can't but it, either. A few minutes later, Ben finds sweatpants , but it isn't cool enough. Daniel likes cool clothes with some style.

So they begin to look for cool things. When they go in to a glasses shop, they find a pair of sunglasses is a good choice. They are cheap and cool. So they picked one and it's only $10.
Then they want to by a CD for Daniel. Ann knows Daniel prefers jazz music. But the latest jazz CD costs $13. They don't have enough money for it.
