The U.S. Products database is a tool equipped with many options to filter and sort its options such as; prices, categories, and countries. This database has AliExpress suppliers that keep inventory on hand in several countries as listed below.
So the great thing is that this feature isn't just limited to the U.S. - there are "Ships from" options for the following countries: Spain, France, Italy, Germany, Poland, Czech Republic, Turkey, and China. Allowing these items to reach customers in these countries quicker.
Shipping times within the U.S. Products database are established by the supplier site. These sites provide their projected delivery times on the product page at AliExpress.
