I like Deseret Industries b/c the quality of the items are top notched (for used stuff). I like that the proceeds go to helping the needy (IDK the exact % but they're a religious organization so hopefully they're doing more than Goodwill).
I find that their non-clothing items to be disorganized b/c they have so much stuff. Maybe they need to lower their prices to get the items sold. I'm not saying the stuff is too expensive, though, I'm just saying that they need to rotate their inventory more. Maybe they could expand their non-clothing space and get rid of their "new furniture" section. IDK if they sell a lot of "new furniture" but I feel like it's taking up too much valuable space.
I recommend this place if you like used shopping (and I do).
