Most people can be uniquely identified by their DOB, gender, and zip code. It's possible they have connected your brick and mortar purchases with your online purchases by matching this information via different credit cards. I believe a year or two ago, Google and Walmart announced some sort of partnership, so between that and your/our credit card companies willing to sell your information at the drop of a hat... it's all connected.
Last year, Nordstoms announced they were tracking customers by setting up multiple wifi hotspots throughout their stores and tracking people's movements via their cellphone's MAC address. I don't know, but it's possible to slurp that information via online sales, too.
Ever since I read that article I've started putting my phone on airplane mode at the mall.
