how come let-trade...

Their description is more like a template. Most of the times their bags do come with dust bag. Just email them and ask if you want to be sure.
 
I got one with a dustbag...and I got one without. I think it depends, but most should come with a dustbag. I'm guessing that bags with a cheaper price point (such as monogram pochettes, small leather goods) are less likely to get a dustbag versus those at higher price points (LE items, Suhali, or large/medium bags).
 
i just bought a bag from them and i forgot to ask for a dustbag. i haven't received it yet but hopefully, it has a dustbag. if not, i'll follow John's suggestion, to go to the store and ask for one :P

@John, will the store SA give a Louis Vuitton box as well? I bought my speedy 30 from LV store in Galleria but the SA just put it in the LV dustbag and shopping bag, no box. I'd like a box for my speedy 30, hope they'll give me one if i show my receipt :shrugs:
