Colonial Electric Supply, King of Prussia, Pa., recently launched its Guaranteed 500 program, pledging to customers that its top 500 items will be in-stock and ready for pick-up or next-day delivery at any of Colonial's branch locations. If an item is not in stock, customers will receive a $25 service credit on their accounts. The Guaranteed 500 program replaces Colonial's Guaranteed 250 program.

“We increased the number of items in this program as part of our ongoing commitment to customer service,” said Peter Bellwoar, executive vice president, sales and marketing. “Guaranteed 500 assures customers that we will have what they need, when they need it, saving them time and money.”

Headquartered in King of Prussia, Pa., Colonial Electric Supply is a family-owned and operated business since 1972. This second-generation company has a central distribution center located in King of Prussia along with 12 branch locations across eastern Pennsylvania, New Jersey and Delaware. Colonial Electric ranked No. 58 on EW's most recent Top 200.
