I wonder why Chase does that? My credit union called me this AM to ask if I'd made a purchase, but it was because I had to cancel the crazy order that was all wrong from last night around 3:30AM and complete another one this morning around 8am that had all the stuff I needed (preorder early in the AM skipped right over allowing me to buy AppleCare or a case for some reason).
They didn't block my purchases, just questioned whether or not I made them.
Chase will block a purchase in a hot minute, though. Every time we take a trip to NorCal, even though we go there a few times a year, they are the first card to reject something as simple as a lunch receipt from Panera bread. Yeah...someone stole our credit card and went to Panera to have lunch.
