I just started a new job at a new company. I haven't been told which day(s) I can work from home, so it is most likely I am not able to ship USPS packages during weekdays of this week. Your USPS packages will be sent out this Saturday at the latest. (My local post office is open at Saturday morning).
UPS is not affected. I can drop off UPS packages to local UPS Access Point at 6-7 PM when I got home from work.
I am sorry for the delay in USPS shipping.
