Hey ladies! I need to send an order to my aunt in ND. I did not get it in time to take it to her this past weekend. Anyway, it is 2 stones and 2 sets of the easy read measuring cups. I have it all boxed up in a PC box with the foam that usually comes in our orders. I am just now wondering if I should send it via USPS or UPS. Any suggestions?? Thanks in advance.
