I would personally pre-pay if I really wanted it. That is the only guarantee of the shortest wait time. Those who pre-paid will get it first before you. You may have to wait until all the pre-pays in line ahead of you get theirs first. As of now, you're not even in line to really get one. Other pre-pays will keep getting in line.Still waiting for a sweet alhambra white MOP necklace... it's been about 2 months. Apparently oos in all of North America.
Customer service did say they've been getting more shipments in May. Didn't pre-pay through my SA because it bugs me to pay in full with no definitive timeline.
Just my two cents, especially if you really really really want the bracelet. I really really really wanted the ring hence I pre-paid.
Good luck to you!
