I have a question. I am looking to create a small site, I will be selling a product that will be shipping from China. Shipping will take a little longer than if I was to ship it from the US. What are some things we can let the buyers know so they are not mad when there package arrives a bit later than usual USA shipping? I want to make it seem as if we are shipping from a warehouse in the US. Also, whats the usual time frame? about a week?
