If you are okay with used try craigslist. Once I saw cd player two technics floorstanding 12 inch speakers and technics receiver for 60 bucks. The seller was over a hour away. I wanted it, but didn't end up buying it. try yard sales, goodwill. salvation army, community aid, saint vincent de paul. Maybe you will find a decent set of used bookshelf speakers for 5 to 20 bucks. I found two kenwood bookshelf speakers that I think came from a mini hi fi system were 7 bucks and 40 watts. If you are okay with any bookshelf speaker brands what about posting a wanted ad on craigslist asking if anyone is giving away free bookshelf speakers that they planned on throwing in the trash. Check neighborhoods before trash day. I have found four small speakers that people put in a box outside to throw away after yard sales or ready for trash day.
