Groupon believes that more efficient targeting will help you to identify repeat customers. Additionally you now have the option to reopen deals for customers. If your customer has hearted qualities that suggest repeat business, Groupon will promote a deal to that customer even after the deal has closed.
The company has also redesigned its dashboard, allowing customers to easily flip between multiple default cities. This is great for people that travel and businesses that have multiple locations in different cities.
