They vary a lot. I've found a few decent classical titles for under $15 shipped. I think I paid over $100 for one rock tape I really wanted. Some good rock tapes can be had in the 25-40 range. If you want Abbey Road or other highly sought after titles, you might need to lay out several hundred. I don't plan to go there. It is enjoyable to pick up something I want at a good price, which happens more often than expected. It helps if you like stuff that was not wildly popular, like this Quarterflash.
