wrecker, you want to get on amazon for the £1.95 premium 200gsm fruit of the loom jobs. 21 colours and mildly associated with slavery, I'd expect, but probably no more than the Gap ones.
My cheap useful thing is a £14 240V inverter for the car. (Belkin, aAazon). Lets you use normal wall chargers for everthing: laptops, phones, cameras, 300W max.
And "used - like new" CDs off amazon too. Cheapest way to buy music.
