Wedding gift?


So I thoroughly believe that you don't HAVE to give a gift while attending a wedding, but we are attending one tomorrow. So there's apparently a rule that you can't spend less than $50???

For real?

My husband and I genuinely don't have a lot of money and we live paycheck to paycheck. I want to give them a gift since they're family. But we definitely don't have $50+ to spend on one.

What are some ideas of cheaper wedding gifts?
