A gun-toting thief who went on an epic 34-day robbery spree in Brooklyn was sentenced to a staggering 68 years in prison Wednesday.

Robert Costan targeted stores in Brooklyn Heights, Park Slope and Fort Greene.

“As part of his robbery spree, this defendant terrorized hardworking employees and business owners,” said Brooklyn DA Kenneth Thompson.

Costan robbed some of the stores multiple times — and allegedly told one repeat victim, “Don’t be cheap like the last time.”

He was busted in 2012 and charged with 12 robberies.
