The casual outdoor look is generally how I dress so I buy a fair amount of my clothes there as well as at Columbia Sportswear - though there's a Columbia outlet not even 5 minutes away from my house. I also tend to buy my Chacos there. In terms of non-clothes related things, the only things I'll buy there are are chain lube, sometimes tires, anything from Garmin, and sometimes gels if I'm already there. I also got my Wahoo Kickr Snap there.
For anything else bike specific I'll go to an LBS or get from Clever Training.
I will say, the two REI stores that I go to in the Portland metro area are generally not hurting for sales. I tend to avoid them on weekends because they're packed on any given weekend, membership sale or not. That said, it's Portland and they have very few competitors here that aren't sport specific.
