Rachel Martin of Little Chute usually bags groceries at Larry's Piggly Wiggly.
In October, the 33-year-old won Wisconsin's best bagger competition.
She's in Las Vegas this week to compete for the national title.
"It's trying to be the best, go fast, and do it as best as you can,” said Martin. "I just care about what I'm doing, no matter what it is.”
Martin will be judged on speed and style.
She lost in the competition last year. She says her strategy this year is to just grab stuff and start bagging it.
