Gorgeous! I have my eye on a Dior messenger and duffle. If you don't mind me asking, how did your spy hobo break? Can't u get it fixed at a Fendi boutique?
to answer your ?, purselova, bluefly.com is a online discount designer source that is particularly famous for having bags no else is selling on the cheap. Everything on bluefly is at least 20% off, and they stock really hard to find brands like Chanel, Chloe, Balenciaga, etc.
Long winded but I hope it helps.
