NEW YORK -- It was not just the deals on Black Friday that caused long lines at many Macy's locations nationwide.
A computer glitch made it impossible to process some gift and credit card transactions.
The problem came at the worst possible time - backing up checkout lines in stores and causing outages online.
Macy's Facebook page and social media accounts lit up with complaints. The problem has since been fixed.
