There have been a few questions via pm and on the thread about shipping. Here is a link to a HBT primer on shipping beer:

Please keep in mind if your box gets broken and is undeliverable, you are responsible for RESHIPPING another 200 oz. AND the payment to ship again! So, to put it in perspective, $10-15 in shipping supplies to ensure safe delivery is nothing compared to buying 400 oz. of beer and shipping twice.
My quick and simple advice, bubble wrap every bottle. And stuff packing paper all around the sides of the box. Hold it shut, shake it, if you hear anything move then you need more packing material. Rinse, Repeat.
