My Costco sentiment score just plummeted.

What's next? Trader Joe's?

So we have Paypal and now Costco building ad networks using customer purchase data.  A lot of Costco members use a Costco issued credit card for third party purchases, I wonder if that data will be used too?

Yet another reason to silo your purchases.  Amazon, Aldi, Food Lion, and VISA know me -almost in the biblical sense- but Paypal, Costco, and the rest just get bread crumbs.
