Wrigley Field Garage Sale ?

When I went to the game last night they had "Fan Appreciation Sale". It was set outside where that outdoor smoker's lounge usually is on the Sheffield and Addison part of the ballpark. Basically it all the stuff the sell on at the gift shop was on sale (Jerseys, hats, t-shirts etc.). But I did see some old stadium seats and bricks for sale also, but I didn't check out the prices. As far as I could tell the only way to enter was from inside the ballpark. You have to enter the stadium then walk through that bar section "Stadium Club" and come back outside.
