According to the Better Business Bureau, the excitement surrounding the Rockies right now will likely set off a series of ticket scams.

"We don't want anyone to get laid off," Boulder/Denver Better Business Bureau president Dale Mingilton said.

For starters, Mingilton says it's important to always who know who you're buying tickets from.

"There are certain vendors who are authorized to sell the tickets. So you want to make sure you know who you're buying from," Mingilton explained.

In some instances, Mingilton suggests staying away from Web sites like Craigslist and eBay.

"If someone says wire me the money and I'll send you your tickets, that should be an initial red flag; once you wire that money, it's gone!" Mingilton said.

Accredited Web sites, like stubhub.com are legit and offer secure sales.

Another factor to point out, according to Mingilton, is that Denver City and County code specifically prohibits anyone from selling tickets for more than their retail face value.

"I can't stop anyone from doing it. And we know it's probably going to happen. But it's illegal," Mingilton said.
