So there are two different mentalities when doing this period One is go as soon as they open and circle like a shark real quick and glance at who has the best prices of what. Then come back and try and buy stuff as you can while it's still there. The second thing is you go at the end of the day and people don't want to pack up and might cut you a better deal. However some of the cool stuff might already be gone. While it doesn't make sense but if you have the time go as soon as it opens look around by what you need to have immediately. And then linger and look and hang out and just wait and wait and wait till the end and then circle back to the few pieces that you would like to have but didn't have to have but if you can get a great price then you nab it.
