I don't know why they don't just show what's on sale near me geographically. You know, two for one Kraft mac and cheese up at Publix. You'd never know that I might buy mac and cheese by data mining me, I don't even really like mac and cheese, but shit man two for one!
The whole targeted advertising idea seems like something cooked up by computer programmers and doesn't seem to actually work on humans. But if ads showed me that toilet paper was on sale somewhere nearby, that's something I might whitelist.
