I've just bought a *pre-owned* Sony PS2 remote control from my local Blockbuster. (Liverpool, Allerton Road.)
The marked price was £2.99 but it scanned at 99 pence.
The assistant told me that 'things' are being reduced in the sale. They had several pre-owned PSPs which, if reduced by the same amount would bring them in at around thirty pounds.
They also had new XBOX HD-DVD drives but they didn't have a price on them.
I don't know if this is nationwide but it may be worth a look.
(*per-owned* because it was still in it's original Sony packaging. It did have a Comet tag on the back so it must have been traded in. Anyone know of a use for the IR receiver that's not needed on a PS2?)
