I just picked up one from Charlton for £15 - they have a couple more marked as clearance. Not bought from Smyths before, they don't come sealed as the cartridges were behind the counter.
I asked someone I know, who was going to be near one of the stores. I received no reply so thought my message had gone unseen. Later on I had a surprise when I heard they had got me one (embarrassed)
Ah I didn't notice it was in-store, as an agoraphobic it wouldn't have been much use to me anyway lol.
In-store only (-: 14 stores have it Bradford Charlton Cheltenham Fareham Forestside Gloucester Ipswich Kidderminster Leeds-Kirkstall Longton Mansfield Newtownabbey Swansea Thanet
Missed it, boo.
