Internet bargain hunters from Southern California who bought discounted round-trip bus tickets through Groupon and Voice Daily Deals to visit Las Vegas on the cheap were left stranded when the buses never showed up, broke down or were hours late, according to a NBC report.

The tickets were reportedly bought for about $45.

There are reports that the buses brought their passengers safely to Las Vegas, but never returned to take them home.

A shuttle from another company was eventually called in to help the abandoned passengers.

MSNBC reported that Groupon said it screened LUX before offering the promotion, and the bus company met its high quality standards

A month later we determined that the merchant was not providing satisfactory service, Julie Mossler of Groupon, told MSNBC.

Groupon canceled the deal and refunded the passengers' money.

When a check was done on LUX's motor carrier permit number on the U.S. Department of Transportation Web site, MSNBC found that the company doesn't seem to have a valid license. Additionally, the company appears to be out of business.

MSNBC reported that the doors of LUX's San Jacinto office were closed and the windows papered.

Voice Daily Deals told MSNBC that it does its best to check out every deal.

We've done a lot of deals and 99 percent of them are really good, said Beth Sestanovich, group publisher of the LA Weekly and Orange Weekly.
