The Warehouse Sale for Denim - worth check out?

Hey guys,

I just got an e-mail from The Warehouse Sale about an upcoming event in my city (Seattle). For those that are not familiar with TWS, they are basically a touring denim outlet that sells denim samples, overproduced items, customer returns, and the like. Here is their website: http://www.thewarehousesale.com/.

Since it's an invite-only event (you have to pay otherwise), I am thinking about just rsvping and checking it out since they boast things like denim at 80% off (they also sell other items, I believe).

Has anyone attended one of these? Would it be worth fighting traffic and giving myself a headache for? I don't want to go if the selection is crappy and the prices are comparable to those that I can find while sitting at home all cozy in my tooth-paste stained pajamas!
