What are the shipping times to the USA?

I need to know this information.

1-I would like to know in which Platform are you planning to buy and which product you want to buy (sometimes we run out of stock), because i have different people for each platform so i can ask the correct one this info. (Amazon, Chuwi Store, Aliexpress etc…)
2-In Which city in Usa are you living?

The size, weight, and value of your shipment can affect the shipping method and time.
