While we're on the topic of sales guidelines, I also think it's important to bring up packaging suggestions. Remember, sellers are sending fairly fragile products potentially over thousands of miles. Here are a few 'musts':

- watch is wrapped and secured using a plastic zip-loc bag and bubble wrap
- watch is placed in a box

I've never had a problem with a watch I've received, but a few were wrapped/protected pretty lightly and put in a fairly flimsy bag. Packages get knocked around a lot when they are being put in a truck or shipped. It's important to pack a watch properly before sending it off.
