I just called the Portland, OR store. They still have the Terracycle boxes available only for employees. They are not available in the store for any REI members or shoppers. They said they had no timeline for returning the bins to the store or anyone who knew when they might have them available again. 

Can you check with the Portland, OR store to see if/when they plan to have terracycle available again?  Does it for into any particular policy from Gov Brown?  Multnomah County had hit the vaccination rate to be considered low risk, so that classification should change soon.
