I just called the 866-vuitton number to check for the green perfo pochette. I may just buy the pochette and keep my damier speedy, but I may exchange my speedy for the mini trocadero that they have in stock (the Valley Fair store has more of the perfo line than the union square store.) My DH bought the speedy from the Union Square store; do I have to do my exchange there, or can I exchange it at any LV boutique?
