- ADAnthony DawsonApr 27, 20265.0The Lafayette post office is a great place for your needs. And their customer service is awesome. They got above and beyond, to make sure their needs are met at their business. Thank you.
- SSSCOct 8, 20225.0Great customer service with professional advice for the better rate and documentation to fill up prior sending. Thank you Navdeep for your service!
- NHNate HuAug 5, 20215.0The asian lady who helped me was super friendly! I'm a foreign student so I'm not familiar with the policy of shipping stuff internationally. But she was so patient and even suggested me to adopt cheaper option when I chose the much more expensive one. Another Indian lady was also very nice too! I usually feel nervous going to USPS because there's one time I only sent a bday card but incorrectly chose the priority shipping which eventually costed me almost $40.... Anyway, so far the best experience I'v'e ever had in the U.S.! Simply made my day!
