Its already less than £3 per disc which is incredible value for money.
If you're not desperately in need of buying it, it's bound to turn up in the Black Friday sales again in Nov- possibly nearer to your target price.There currently is no point my buying it, but will probably do so when i return to the UK for my holidays in August. I can cross my fingers for £2 or £2.5, ok probably not but i can wish.
