Affordable wedding bands?

Megan • 22 • Married • TTC #1

My fiancé and I are having a Civic Marriage ceremony next month and are looking to order a pair of wedding bands that are not only affordable but will last up to 5 years (we would like to upgrade our bands on our 5th wedding anniversary because his parents did that as well.)

If you're married, where did you get your bands?

Or where does anyone suggest I look?

Thank you in advance!
