I gave my email information to Kohl's in order to get discount coupons. Of course this brings a daily email but this is no problem since I have an account strictly for companies who are likely to spam.
So, today I go looking for a coupon as Mimi and I will likely be shopping there tomorrow. I open their latest email and here's what I read:

Now, I find this more amusing than alarming, but it definitely shows that they link their email coupons to the customer and have kept track of what I buy with them. If I had shared the account with an unknowing spouse it might have been less amusing!
