I cannot comment on the place itself because I've never been inside. But thanks to the review of a friend, I found out just how easy it is to donate.
I had some couches and other stuff that I won't be needing after I move in a couple of weeks. So I went to satruck.org to schedule a pickup online. It was really easy to navigate through the website, tell them what you have, and find a date for them to come and pick it up. Sure enough they came, and got the stuff out of apartment pretty quickly.
There are a couple of negatives. It's hard to find the pickup page from the Salvation Army's homepage. And they will not give you a pickup window until the morning of the pick up. Not a big deal if you just have a couple of bags for them to pick up at your door, but not good if I had to be somewhere during the day when the window was suddenly available.
