What They Sell

Shopping Tips

  • Call ahead at +1 605-863-0727 to confirm hours before visiting, especially during off-season months when small Wall, SD shops may keep flexible schedules.
  • Arrive early in the week or right when they open — that's typically when freshly donated or newly priced inventory hits the floor at shops like Nanna's Mercantile.
  • Bring cash as a backup, since small independent thrift stores in towns like Wall don't always have reliable card processing.
  • Keep an open mind and browse every section — Nanna's Mercantile-style shops often hide the best finds in unexpected corners among everyday items.
  • If you spot something you love, don't wait on it. Thrift inventory is one-of-a-kind, and at a small shop in Wall, SD, that item won't be there on your next visit.

Before You Go

Nanna's Mercantile has not yet published official hours online, so it's a good idea to call ahead at +1 605-863-0727 before making a special trip. As a small independently owned shop in Wall, SD, hours may vary by season — particularly given the town's heavier tourist traffic during the summer Badlands season. Reaching out directly is the best way to confirm current availability and avoid a wasted drive.
