as far as i know, prada hawaii was the last one to get a shipment, a few weeks ago... i was on the waitlist for that, but they were only getting 10 bags or something, and i was beyond that on the waitlist, and i haven't been called since.
i finally gave in and bought mine on ebay - there are a few legitimate sellers, but they are selling for a few hundred dollars over retail. when live.com was offering 25-35% cashback, this came out to be at retail price, so i kinda lucked out...
just check though that these pictures are indeed the same pictures for the same EXACT bag you are going to get, ask seller to email you more pictures... they're not watermarked, and i would be wary if they stole them from someone else.
the other option is checking international stores (asia, europe)? i heard they are not as popular there, so you may still have a chance. maybe.
good luck! i am SO IN LOVE with my prada fairy astro, i definitely recommend this bag to anyone else. it is just PERFECT!
