Lots of people have lots to say about Groupon, which is a daily deals website. I have purchased quite a lot in Australia from Groupon and now, a number of things in America.
Groupon can be a great way to save money on entertainment or food in the places you visit.
You can sign up for daily emails which have deals from a range of locations.
Great way to find out about hidden treasures in the places you visit.
Ensure that you read the conditions very carefully. Often the time you can use the coupon is very limited and may not meet your travel requirements.
