I'm currently 34 wks and got vouchers from Tesco in the post today for nappies. How do they know? I've not bought ANYTHING baby-related, except a cot from John Lewis. I've not even searched online at Is it some sort of Voodoo?

Companies pass each other details (usually a thing to tick at bottom of some form/survey you have filled recently if you do/do not want your details to be passed on) maube?

did you get a bounty pack?

I always make sure I untick/tick boxes so my details aren't passed on. No bounty pack either. Maybe they have some sort of pregnancy diviners working for them smile

These companies have so much data they can just TELL. Serious. My cousin used to work for Sainsburys and they could predict divorce based on nectar card activity. Mad.
