I know that various items from Orange have been mentioned elsewhere - but I think that unless someone was looking for a specific phone they may be unaware of the number of random bargains available.
I popped into all three Orange shops in Manchester at lunch. There are loads of accessories manually marked down and each shop had different things (at different prices). The same will go for other orange stores across the country.
I suggest that you pop in there if you need any accessories. There was loads of Bluetooth stuff but I picked up a set of Sennheiser PX100 headphones reduced from £29.99 to £9.99 (the last ones in store)
Most of these deals are just one or two of each item in shop - so its really a lucky dip.
