Pleasant surprise I'm sure! I would def keep that in mind when you're ready to get one of their cards. I started with the Chase Freedom almost 2 years ago and I absolutely love them! The cash back categories is cool but moreso is the total package of the rewards program. I had no clue about it at the time, I was just applying because it was one of the first advertisements I saw lol! But now I'm very familiar with their program, their 5/24 rule, etc. I recently got the Chase Sapphire Preferred through a preapproval link on my online account and attempted the Freedom Unlimited (for the intro 3% cash back) but was denied immediately. It wasn't because of the 5/24 rule but was denied because I applied right after applying for the Sapphire (probably not very wise but I was anxious lol!). Anyhow, a few days later I got my denial letter ("too many requests for credit") and called them to request they override the denial and they graciously did a manual review of my credit report and approved me! So now I have the 3 card I've wanted! Only one now I'm looking forward to is the Ink Business but that will be after sitting for probably about 6 months to clear out some stuff on my report.
Some people chase Chase. Others will have Chase chase them if there is reason to believe there will be benefit. In your case the chaser is a mega bank that really wants to do business with you. All you have to do now is to tell Chase to fetch your new card.
