Hey, I need to understand Bricklink a bit better. As I understand it, it's a bit like eBay for lego. They have the benefit of having one reference database, so you don't have to worry about discrepancies between how different sellers sell the same item (awesome idea). So, you can put together a shopping cart, but can you only buy from one vendor at a time? When/where do you see shipping charges? Who can give me a bit more of the skinny?
