Now it seems I'm going to get hammered with daily emails from them telling me what I need for my bike, and every time I use the pc google has decided to advertise the taillight I've already bought. Still it beats getting ads of womens clothing presented to me as they think my wife is the user. And now while I'm in a mood, the grammar police are insisting I add commas here and apostrophes there all the time and I can't hurt a programmes feelings by not complying.
If you want a laugh I used to frequently get ads for running shoes and gear, I've one working leg and barely reach 4mph at my fastest.
