The USPS does not deliver mail on Sundays, except for Express Mail.
Depends on which service you use. USPS Express mail: Overnight USPS Priority mail: 2 -3 business days USPS First Class Mail: 2-5 business days
It can take anywhere from a couple of days to several weeks. There are no guarantee's on priority mail during the holiday (USPS). The only guaranteed mail delivery is USPS Express Mail.

No, you cannot use a Forever Stamp to mail a domestic USPS Express package. Forever Stamps are only valid for First-Class Mail, which includes letters and postcards. For Express Mail, you need to pay the specific postage rate for that service, which is typically higher than First-Class rates.

First Class Mail is delivered in three to five days.
The USPS does not mail from China, they have their own postal service. kurtdriverUSPS does ship via International Express USPS both from and to China; Priority Mail as well. I just verified this via their website. Delivery times are guaranteed within a timeframe and tracking is standard on Express.
Priority Mail Express generally is delivered the next business day.
