"Hey did you see the business cards she looked up? Lol. Let's put the exact same one she just about bought into an ad post on her Facebook to remind her of the purchase she never completed."
I'm not buying them now on principal!
"Did you know that Mariana loves Country Road!? She's looked them up like twice now."
"Really, well what a coincidence. Country Road is having a great sale so I'll just pop a sponsored post up on her Timeline because she doesn't actually 'like' Country Road on Facebook just yet."
And oh how I was tricked. I bought 4 pieces of (really nice) jewellery from Country Road (for a great bargain) before I realised what a sucker I was.
Beware. They're always watching you.
