They have a 1/3 rule thing going last time I been on their forum.
The 1/3 rule for shipping only applies to orders placed in the first month. They said that after that, they would ship orders normally, as they do now: by order number.
Keep in mind there's a lot of froth and heresay in the forums about BFL, but I think you'll find that our customer service is excellent after having properly staffed up over the last 12 months. We have a large team focused on serving our customers.
+1 I sometime have to wait a day or two to initially respond if they're busy, but they always respond quickly after that, and have helped me out plenty of times.
I hope I get a response too. So far I am on day 3 of waiting for them to get back to me on my email.
