One lucky new Core-Mark member will win an all inclusive vacation for two.

A new promotion from Convenience Store Alliance (CSA) is offering an all-inclusive vacation for two to the Hyatt Ziva Los Cabos resort in Cabo San Lucas, airfare included, to one lucky c-store owner.

From now through March 31, c-stores that convert all grocery and tobacco purchases to CSA’s national Core-Mark program will get two entries into the trip-giveaway drawing. Stores that convert from April 1 through June 30 will receive one entry.

“We know it’s a big decision to switch grocery suppliers,” said CSA president and CEO Mike Lawson. “So we’re offering the getaway as extra incentive to an already-lucrative chain-store deal. The odds are definitely worth betting on, but even the owners who don’t win the trip will still be taking their savings to the bank from the national chain store deal.”

California retailer Tom Prewitt, who converted to CSA’s Core-Mark program in early 2015, said, “with the amount I’ve saved, I could pay for a manager’s salary for a year. The service has been great, the pricing is great – everybody’s quite happy.”

“The odds of winning the trip will be about one in 200,” said Lawson. “But the odds of saving something with CSA is still 100%. Our Core-Mark customers save enough money to take their entire families on vacations for years to come.”

In order to qualify, stores must still be in Core-Mark’s database, actively purchasing through CSA’s national account at the time of the drawing.
