I'm hoping I won't have to make the change, seeing as my best friend/roommate will be here a few months longer than I will and won't have to bother BFL about it... either way the whole situation makes me far more nervous than I should be.
When I placed my order which was late Feb, they stated they were in the final stages for shipping; we are now past mid May. I cancelled my order through paypal early April as there were further delays and no guarantees made for delivery.
My advice is get in touch with them to see if its possible to change address, or cancel your order if you paid via CC or paypal.
I have had an order a month ago from Enterpoint, paid a small deposit for some boards and today I paid in full to be delivered by this week; manufacturing and delivery time < 4 weeks. BFL should take example of how these companies make business and stop taking pre-order money if they cannot promise to deliver in a timely manner.
