An article about USPS shipping and delivery time:
When you order something from the United States Postal Service, you can expect your package to arrive within a few days, but usually within a few days of when you placed your order. However, there are occasional delays, which is to be expected with the massive amount of mail that the USPS processes every day.
As long as you have given your shipping address correctly, the USPS should be able to deliver your package to your doorstep.
