Ok, I'm not trying to fuel a hopeless fire, but a friend who knows a manager at the Ontario location said that they had finally sealed the deal on the old Sam's space, and they are shooting to open in March. Still can't find any thing "official" online, but did find this post on the Frankel & Giles blog from Sept. They are in the real estate biz in the area...
We've emailed Trader Joe's corporate to see if there is any validity to this rumor. If we hear anything we will obviously post it. Our fingers are crossed.
