Bought a 30L backpack today from Clas Ohlsen for £9.99. I think it might be a clearance deal because they had a near identical bag for twice the price. I know a lot of cyclists don't like backpacks because of Sweaty Back Syndrome, but this has a mesh airflow thingy that's supposed to help, and I prefer the convenience of a backpack over panniers if you're just nipping out to the shops.
They also have a Shimano gear cable set (inner and outer, front and rear) for £5.50.
