text: Not sure what you can say about a post office I needed to mail a package on a Saturday and looked up post offices on Yelp after taking a grad school exam The directions were good and I found the place with no problem This location however is not open on Saturdays the window If you want to mail anything on Saturdays you will have to use the Automated Postal Center APC machine nnThis location is open only Monday through Friday I do not live in Mesa but judging from all the locals coming in asking what was wrong I take it they are not used to this either I stood in line a long time behind this lady who was mailing a litany of large envelopeslong enough to tell several people to read the hours posted on the outside doors nnThe post office is beside the Mesa airfield and looks fairly new I did not have any issues other than expecting to be inout and that was not the case There is only one APC that I saw so if there is one person with an armful of packages to mail bring a book
