I have shipped hundreds of packages through the Hamilton post office over 16 years and never had a problem. Employees are efficient and reasonably friendly.

Never have any issues with ups, but the usps seems to ALLWAYS find a way to mess up my shipping. Either marking them delivered and delivering them 5 days later or putting them in the completely wrong mailbox.
