My closest LFS doesn't even take fish back from people, so you have to be careful. But they are super good at keeping their fish healthy and even treat diseased fish in their tanks and don't sell them till it's all clear. Alongside reasonably good prices ($24+- dollars for an 8" Oscar) it is a good trade off.
Chain stores don't seem to be all too good at healthy fish? Lucky there are none here
