They may be necessary, though having 4 splashed on the page is too much, however i am quite disturbed by the fact that a site i recently looked up and purchased an item from now appears when i open out AB. does that mean that one is being targeted, and that your details are now known. Perhaps the ad is only privy to me, but i don't like this one bit.
I am concerned that I have a freaky looking nun glaring at me on this page....
ED have a word and don't put horror-type thingys on the site please! I will never sleep! ;)
