Seems like a legit purchase to me!

Mine flags my rent payment literally every month when I buy a money order at the Walmart less than a mile from my house. This has been to the same merchant on the same date for almost four years. Even so, they have never once flagged any of my travel.

I’ve started just using the ATM in Walmart and paying cash, because a $1k ATM withdrawal is fine, and they refund ATM fees.
