My family and I were prepping for a trip to the Dells in Wisconsin. And I looked up tickets for the Army Ducks. At first glance when shopping Groupon I thought, "Wow, what a deal!" Four tickets normally cost $120, but my price was only $75. So I bought them. Later, I clicked on the hyper-link that took me to the vendor that sells these tickets year round for these boat tours, and they were cheaper than Groupon! I was irritated when I saw this. Groupon... not only did they inflate the prices to make the mark down look huge, the final mark down wasn't the best deal after all. I contacted customer service about this, they acknowledged the fact that I was correct, offered a refund. I asked if they could just price match it to make it simple. They said no. Lesson learned, don't be a sucker, it always pays to shop around.
