Natalie Joy Miller, 38, has saved $5,000 over five years by thrifting birthday and Christmas presents for her son, Artie.

The Portland, Oregon mum has been collecting second-hand treasures since she was 16, long before Artie was born.

This year, she spent under $150 on 13 birthday gifts, including a Dutch oven matching her own, and $154 on 22 Christmas presents.

Natalie says thrifting is both cost-effective and sustainable, adding that Artie loves his unique finds.

She dismisses criticism, saying, “He’s a kid—it's more individual and cool.”
