I've lived in un-incorporated Oak Brook (mailing address) for 22 years. The building complex is considered "high visibility property" as it consists of Town-Homes and Condominiums, one of which facilitates a known restaurant. Through the years many people have moved on. The postal carriers have always been able to re-learn and familiarize themselves quickly with the changes. I have always received great service from all the carriers. Through the years I have tried mailing some items via other services, "U-Mail," "Pak-Mail," and the UPS Store but have always return to USPS in Oak Brook. The PRICES are better, service FRIENDLIER and more HELPFUL and delivery is just as QUICK as any other method. Thanks for everything!
