Wedding Ring Advice: best place to find something under $150?

Me and my partner are getting married this month. Due to immigration costs surpassing 3k, we are on a tight budget.

What are some good options for wedding rings?

We want something that will hold up over time but don’t need anything fancy!

Also, has anyone done a courthouse wedding before? Seems to be the most affordable option given our circumstances.

Any advice would be greatly appreciated!
