I'm confused... Radish Underground has the PDX Collective sale posted on their site as being Sept 15 & 16 at the Laundry. ???? And your link above goes to the BargainHunting site, not PDX Collective.
Ah, that would be because I had a massive brain fart and confused the names. Fixed now. I'm going to go ahead and use the excuse that I'm getting married on Saturday and am super effing distracted while I still can.
