Because it's inconceivable that a pregnant woman might be buying things for someone not pregnant. Anyhow, as the others pointed out, it's part of the randomness disguise. But this type of marketing is creepy and invasive. No one likes this because we're basically powerless to choose an alternative. My fiance is marketed tampons on Facebook during the correct time of the month. Because of things she bought on a shopper's card. Disturbing. The real impact will be when your rates on all types of insurance are affected by this data. Or when employment decisions are made.
