I think Blue Fly's prices are rather high in general. Nothing is ever really THAT cheap. The most I've seen MJ bags marked down is 20% - sometimes they have special sales where there's an addtl' percentage off and/or where you can subtract $XXX from your purchase price. They do get some bags & SLGs that were HTF and not carried at most retail stores (i.e., the Birds of Paradise Marky), so sometimes it's worth it, but I think when it comes to some of the more "common" handbags, i.e., Stam, Cecelia, etc you'd be better off keeping your eye on ebay/bonanzle or checking w/retails stores for returns/markdowns.
These went down to 60% off at Nordstroms, and while there weren't many left when that happened, it still makes an $1100 price tag still seem kind high. Did you check out on the one on the bay? Get yourself pics of the tags from inside the pocket and you should be good to go -- it's a BIN/Best Offer too!!
