Groupon, a popular website that offers discounts on local goods and services, has made it possible for users to resell their unwanted vouchers on third-party websites. This new trend, known as "Groupon remorse," is driven by users who have purchased more vouchers than they can possibly use. These users can now recoup some of their investment by selling their vouchers to others at a lower price.

There are several websites that allow users to sell their Groupon vouchers, including:

* Yipit: Yipit is a website that allows users to find and purchase local deals. The site also offers a marketplace where users can buy and sell Groupon vouchers.

* DealCatcher: DealCatcher is a website that aggregates deals from various sources, including Groupon. The site also offers a marketplace where users can buy and sell Groupon vouchers.

* Swappa: Swappa is a website that allows users to buy and sell used electronics. The site also allows users to buy and sell Groupon vouchers.

When selling a Groupon voucher on one of these websites, users will need to provide the voucher number and the redemption date. They can then set the price that they would like to sell the voucher for. Once a buyer has been found, the user will need to transfer the voucher to the buyer.

The process of selling a Groupon voucher is relatively simple, and it can be a great way to recoup some of your investment if you have purchased more vouchers than you can possibly use.
