When she's not responding to you, she's still working on your order.
Typically, what happens for me is:
1. I say I want X, Y, Z
2. She gives me the price
3. I pay (this seems to be where you are)
4. A couple of weeks later, she gives me QC pictures and says she's done X returns, gotten so-and-so fixed at her watch smith, and run them all for a week without problems. If there are issues still outstanding, she asks what I want to do about those.
5. I say to ship them out.
6. She gives me a tracking number (or two or three depending on how many watches I ordered...)
7. They show up about a week later, I send her some pictures and comments to thank her, enjoy my watches.
8. Flip half of them because I want to try something else.
9. Flip another one because there's a new release I want to fit into the budget.
10. Ask Lucy if she can get the new release and go back to 2...
