Spotted these on the isle end 'plastic strips'. Neat little 2Gb USB flash memory stick for just £2.49. Seems a very good price, though claimed original price of £9.97 is less realistic.
Tesco own brand, model WG 1009. Doesn't appear to be on Tesco Direct so no picture, sorry.
Saw it in Redditch (plenty of stock) but no reason to think it isn't national.
