Tiffany Stevenson is among Sam's Club members who intended on shopping at the South Tampa location, only to find a "closed" sign on the front doors.
"We've had the premium membership and this is kind of disappointing. It's a shame because we don't have very many places like this in south Tampa."
"I can't believe it, this is crazy," added customer Mike Haker.
The South Tampa Sam's is among dozens that are closing or will close around the country.
The company says the closings are part of a "realignment strategy". The South Tampa store is expected to reopen Friday, then close permanently in a few weeks.
