In most cases records of routine purchases are documents available for purchase. Want to know what I bought last time I went to the grocery store? You can buy that. Want to know what I bought on AliExpress? (hint: it was cameras!) This information is "out there." Doesn't take much to dig it up, no warrant needed. Terms of use of most online shopping sites as well as physical store loyalty cards let them sell this information to whoever wants it for whatever purposes.
Presumably, Homeland Security bought such information; I doubt a warrant would be needed in this case.
It's one thing for "big brother to be watching what I'm buying" and another for Homeland Security to purchase commercially available databases of who is buying in quantity items they consider of interest.
Remember when Radio Shack used to ask for your address when you just wanted to buy a pack of damned AA batteries? (their batteries sucked by the way) They wanted to know who was buying what and use that information for marketing purposes.
I'm interested to learn more about this, as this is not an area of expertise for me.

Yes - many pro-business groups and Government groups want more power and more rights over data.
Yes - we, the people, need to find ways to halt that in order to maintain a balance of power for the stake of liberty.
Warrants have been a key part to the theory of checks and balances in our legal system. We should not be doing away from that.
1) We've been discussing the issues of massive data available on people at least before 2000...
