I've never gotten any pre-approval from them from that site. I've just cold apped for their cards. I honestly don't know why they don't have a better pre-qualify/pre-approved software. Mine just show up as "we recommend".
For whatever reason it's their business model. They do extend valid prequalifications that can be for a specific card, or sometimes the option to pick one of several named cards, to existing clients that they have targeted.
