If you never needed or wanted something in the first place, you end up spending extra money which goes against the concept of making savings. For example, getting a daily deal on a hotel for a trip you didn't plan to go on could turn out to be costly as you will have additional expenses to pay for whilst there.
If you plan on getting everything you can out of daily deals sites, it is a good idea to get yourself organised. Expert daily deals shoppers organise their daily deals in a folder by expiration date to ensure that high priority deals don't go amiss.
To get your daily deals sorted, create reminders on your smart phone or computer to remind you when deals are due to expire. Take McDonalds for example, they once offered customers half price fries and Big Macs through Groupon. However, if you go in-store any day of the week, you already get 30% for buying these products together, meaning that the daily deal only saves you 20%, not 50%. However, some people are so captivated by the great discounts that they wind up spending more than they would have otherwise. In order to get the most out of daily deals sites it is important to only go for the deals that you need.
