Hello, I am planning to start a store in which it takes 6-9 days for me to get the product but it  would be   2-3 week shipping on my website. Am I allowed to do this ?. 

I want to start a store in which I live in the USA but my product will be in China and I would like it to be shipped from China to the country of wherever the person that purchased it resides how can I do this legally ?
