Compliment

My friend Max's mom has what I believe to be the coolest job ever. She works at the Lego store. If they would let me, I would live at the Lego store. My second choice would be to live in Max's playroom because he has almost as many legos as the store.

I told Mommy "Max has all the legos because Jen has a compliment at the lego store."
"A compliment?"
"Yeah, a compliment is when you have a job and you buy legos too fast. That's a compliment."

I think the word I was searching for was "discount" but "compliment" is close enough.
