I'll be honest, I've shopped at the NW 39th and Portland WinCo dozens of times and while it is my 2nd favorite grocery store in the Metro (behind the Crest at SW 104th & May), I've never felt like that store was doing incredibly well in terms of business. Possibly I'm just good about going during off-peak hours, but that parking lot just never seems to be very full for a store that's light years ahead of every other option within a 5 mile radius.
