1. How much does the lock + key for the Speedy 30 cost? I bought a lock + key for my Mini Sac for $24 at the boutique, but I don't know if all of the locks are the same price. 2. Is it possible to get a dustbag from the 866.VUITTON number? I've already tried asking for one at the boutique, but they didn't have any extras. Thanks in advance!
