What FreebieAgent noticed
Sonic Suds Express is a legit regional car wash chain operating three locations across South Carolina. The offer requires signing up for their text club, which is a pretty standard play for car washes looking to build their customer list. You'll get one free wash upon signup, though typical text club deals come with occasional promotional messages after. The catch is location: this only works if you're near Greenville or Simpsonville, SC. It's a solid deal if you're in the area and don't mind texts about their promotions.
