I don't buy enough from Amazon for them to aggregate info about me. On Newegg, I buy a fair amount of stuff but it's for different people so they probably can't make heads or tails of what I do either. My grocery purchases may or may not be on my shopper card, and down here in Texas no retail chain even has shopper cards

As far as Google aggregating my info goes, so what? As long as they don't sell the info itself to anyone or turn it over to Sav...er...Uncle Bar...erm...Sam, I'm cool. If having all my info means they advertise hot cars, cool computers and college scholarships to me, I'm perfectly fine with that
