Be aware of "Final Sale". I just paid over $100 for coupons for Architecture Tour of Chicago (boat ride) that turned out to be worthless, because I couldn't use them during Labor Day Weekend (which was the reason for purchasing) Then they refused to return my money because the sales were "final". What?! They cannot return my money I paid for an e-mail with bar codes I didn't use? Not to mention that it was just $7 off of original ticket price ($36 vs $43). I ended up buying another tour for $39 dollars directly from Wendella Tours & Cruises website. Total scam! Please do not use Groupon. Such dishonest company has to go out of business!
