I was interested in ordering the damier pouch that usually comes in the Marais and ordering the chain so I could use that as a mini pochette. I will be in Vegas this weekend for 4 days so I thought of ordering it from them so it would be there when I got there. What are my obligations if I do order? Do I pay for it up front? What do I do if I decide I don't like it? Since that pouch was bigger than the mini pochette, I thought it would be a better deal.
