Sometimes you just have to be patient. I suggest you talk to your LFS, and see if he brings in Oscars from a regular supplier or from a few different ones. I usually try to make it around to most of the petshops in town (the good ones anyways) about once every few weeks, seeing what they got in and seeing if anyone traded something in I have been looking for. Oscars are pretty hit and miss on shipments, with really nice tigers ordered more and more infrequently, but definitely not rare by any standards. Just keep looking, and you will surely find what you are looking for.
