Smalls and mediums go quick, within the first couple hours of the expo if I remember right. By early afternoon I think larges were gone as well, I don't know exactly what time. I remember because one of my friends was trying to get a L marathon jacket and had a later VQ and I offered to grab one for them since I was there early, and they said they'd take their chances but they were gone by the time they got in. Someone feel free to correct me though! If you are a S-L you can probably preorder and easily find someone to buy it off you for list price, and then just try and purchase with your discount at the expo if you get in early enough. I'm not sure if XL and above are as easy to sell.
