Re: Hmmm...
Haunt the charity shops and disk exchanges. I volunteer at a BHF shop and we check all CD's for scratches to ensure they all will likely play.
On Friday we got two loads of vinyl donated, one in a convenient cardboard box full of LPs with another a collection of 9" singles. A guy came in, asked if we had any vinyl and the LP box got dragged out for him and I grabbed the singles of which he bought several. A very happy conjunction: very happy customer and the BHF got some money.
