What ever you do, DONOTUSETHISSTORE!!! They may advertise Post Office services but, as they will clearly tell you, they do not work for or with the PO. Therefore, they do not need to abide by PO prices, such as flat rate shipping boxes/envelopes. So your 5.80 flat rate box is now 8.80 or more depending on weight and destination. On top of that, the service is INCREDIBLY slow. In a nut shell, if you want to pay way more, have a lot of time to waste and don’t care about customer service, then this is your place. Otherwise, pick a PO and visit them instead. The program will not let you pick NO stars but that would be my choice.
