If you like getting a good deal online your personal information might have been compromised.
The 'daily deals' service called LivingSocial was hacked over the weekend and you could be one of 50 million customers affected.
Hackers accessed personal data, including names, birthdays, and some password information.
LivingSocial says credit card information wasn't taken but it's telling its customers to change their passwords. And warning that if they use that password on other sites, they should change it there as well.
