I’ve heard of GroupOn, but never thought of using it.
Is it a place to find marked down tickets?
Yes and a myriad of goods and services.
Pick and choose carefully, and where you know what the actual price is.
For example: Cowboy's Brazilian Steakhouse in Columbia, SC. Regular dinner for two is $75. With Groupon, they throw in a bottle of wine :)
I use Groupon a lot. Great deals for restaurants and activities. We were in Hawaii in September and used Groupon to pay for all our activities. Volcano chopper ride, ziplining, etc. A lot of people don’t know that if you call the company direct they’ll match the Groupon deal without you actually having to buy on Groupon. That way they don’t have to pay Groupon. lol We’ve done that a few times. You can also get awesome trip and hotel deals.
