I have just got back from P C World in Wrexham, Where they had a pallet full of brand new 15" Advent TFT monitors for sale at only £19.99 each. The Model number is F159.
I know that these days 15" is considered small but at only £20 I think it was a good deal.
I have had a look on their website and can't see it so they must be shifting old stock, so might not be in every store but worth a look.
Also this is my first deal so if I have made an error please forgive me.
