EDIT - now dropped in price to £10.99!!!
This has dropped by another few quid since it was last posted a few months ago. The Viking 1GB SD card is now £11.74 including FREE delivery from Savastore. Another good point is this - it comes with a standard 5 year manufacturers warranty!!
These are so handy to have as spares for your digital camera...
