The Goodwill on South Lamar is one I have been to several times before, and it's always been pretty good to me. It's cleaner and better organized than your average Goodwill, which is always a plus, and it uses the same basic pricing structure for most items. However, this store also has a separate section of "better" clothing (lots of gently used and new Banana Republic) that are priced slightly higher (around $10 an item). For someone who doesn't mind going through and looking for these things herself, that's a bit of a drag, but for a less dedicated thrifter it might actually be a plus.
On my most recent trip, I didn't look much at the clothes--I've previously been discouraged by a lack of plus-sized selections. I spent most of my time in the housewares section, which was great. It's a good mix of used and some vintage pieces and quite a few Target seconds or clearance items. Things are reasonably well-organized and priced pretty consistently.
The book section in this store is only average sized and hasn't ever begotten much for me. The furniture is in a separate building, away from the rest of the store, and is very hit or miss.
