What FreebieAgent noticed
Harper Auto Wash operates four locations around Knoxville, Tennessee (Parkside, Bearden, Alcoa, and Hardin Valley), and this is a straightforward new-customer offer. The catch is the SMS opt-in requirement to receive your barcode via text, and you're limited to one wash per phone number. The brand appears to be a regional operator with a professional website and multiple locations, suggesting legitimacy. This is a solid deal for anyone in that area willing to trade their phone number for a $29 wash.
